Ruby version update

[grvsachdeva]

Hi, we are using very old ruby version 2.1.2 which is troubling with the installation.

Errors I faced:

1. Error running '__rvm_make -j8' while installing ruby 2.1.2

Solved by rvm get head
After completing installation of ruby version, I switched to it.

2. I ran bundle install and got below error

ZenTest-4.11.1 requires rubygems version < 3.0, which is incompatible with the
current version, 3.0.2

I deleted the Gemfile.lock and ran bundle install again.

3. After that I got this error in bundle install

Gem::RuntimeRequirementNotMetError: nokogiri requires Ruby version >= 2.3.0. The
current ruby version is 2.1.2.95.
An error occurred while installing nokogiri (1.10.1), and Bundler
cannot continue.
Make sure that `gem install nokogiri -v '1.10.1' --source
'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  aws-sdk was resolved to 1.5.8, which depends on
    nokogiri

Many new user would be going through the same situation if they try to switch from plots2 to mapknitter and without using too because our dependencies are old and conflicting.

@jywarren should we update ruby version and important gems first to make installation easier for contributors? Thanks!

Cool! I am opening PR, I think we can update to latest stable release 2.6.1. What do you think?

Update: @jywarren lets update to ruby 2.4.4 so contributors don't face issue while switching for contributing from plots2 to here. Also, I tried but there are some error due to docker I guess, so need help.

Thanks!
