Install yarn on a CI self-hosted worker

[andor0]

Motivation

There is Markdown linter (https://github.com/remarkjs/remark), it requires yarn.
I plan to add remark check in CI (#220).

Suggested Solution

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update
sudo apt install yarn

or

npm install --global yarn

Thanks for pointing it out..I will update the runner installation to add yarn, It will come with our next runner update

@andor0 DOne, you can freely add yarn or npm to your workflow

The installed yarn looks strange.

$ yarn --version
0.32+git

$ yarn --help
Usage: yarn [options]

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  --generate-manpage=TEMPLATE
                        fill in manual page TEMPLATE
  --output=FILE         write output to FILE, instead of standard output
  -n, --no-act, --dry-run, --pretend
                        do not actually run any tests, merely print what would
                        be run
  --no-no-act, --no-dry-run, --no-pretend
                        opposite of --no-act
  -q, --quiet           be quiet, avoid progress reporting, only show errors
  --no-quiet            opposite of --quiet
  -v, --verbose         make progress reporting be more verbose ("wall of
                        text"), instead of a one-line status info; this is
                        turned automatically if there is not terminal
  --no-verbose          opposite of --verbose
  -s SHELL-LIBRARY, --shell-library=SHELL-LIBRARY
                        include a shell library for the IMPLEMENTS sections to
                        use
  -r SCENARIO, --run=SCENARIO
                        run only SCENARIO (this option can be repeated)
  --tempdir=DIR         use DIR as the temporary directory for tests; it
                        should be empty or not exist
  --env=NAME=VALUE      add NAME=VALUE to the environment when tests are run
  --snapshot            make snapshots of test working directory after each
                        scenario step; you probably want to use this with
                        --tempdir
  --no-snapshot         opposite of --snapshot
  --timings             report wall clock time for each scenario and step
  --no-timings          opposite of --timings
  --allow-missing-steps
                        allow scenarios to reference steps that do not exist,
                        by warning about them, but otherwise ignoring the
                        scenarios
  --no-allow-missing-steps
                        opposite of --allow-missing-steps
  --require-assumptions
                        require ASSUMING to always pass
  --no-require-assumptions
                        opposite of --require-assumptions
  --shell=SHELL         run IMPLEMENTS using SHELL
  --shell-arg=ARG       use ARG when running shell
  --cd-datadir          change to DATADIR when running commands
  --no-cd-datadir       opposite of --cd-datadir
  --stop-on-first-fail  stop if any scenario step fails, don't run more
                        scenarios
  --no-stop-on-first-fail
                        opposite of --stop-on-first-fail

  Configuration files and settings:
    --dump-setting-names
                        write out all names of settings and quit
    --dump-config       write out the entire current configuration
    --no-default-configs
                        clear list of configuration files to read
    --config=FILE       add FILE to config files
    --list-config-files
                        list all possible config files
    --help-all          show all options

  Logging:
    --log=FILE          write log entries to FILE (default is to not write log
                        files at all); use "syslog" to log to system log,
                        "stderr" to log to the standard error output, or
                        "none" to disable logging
    --log-level=LEVEL   log at LEVEL, one of debug, info, warning, error,
                        critical, fatal (default: debug)
    --log-max=SIZE      rotate logs larger than SIZE, zero for never (default:
                        0)
    --log-keep=N        keep last N logs (10)
    --log-mode=MODE     set permissions of new log files to MODE (octal;
                        default 0600)

  Peformance:
    --dump-memory-profile=METHOD
                        make memory profiling dumps using METHOD, which is one
                        of: none, or simple (no meliae support
                        anymore)(default: simple)
    --memory-dump-interval=SECONDS
                        make memory profiling dumps at least SECONDS apart

Oh seems like a very old version on the runner
