moving to github actions from travis

moving to github actions! Also note Cypress setup here: #402

Hmm. Grunt should be installed already: https://docs.github.com/en/free-pro-team@latest/actions/guides/building-and-testing-nodejs#installing-dependencies

[jywarren]

Hmm. this grunt location issue is causing trouble...

Hmm. Just noting that this all runs fine in GitPod:

          npm install grunt grunt-cli
          node_modules/grunt-cli/bin/grunt build
          node_modules/grunt-cli/bin/grunt transpile
          node_modules/grunt-cli/bin/grunt jasmine
          npm run start:ci

I believe this is working now, but tests are failing!

[jywarren]

for example getting a lot of

  6) Fractracker layer removes markers from the map and the layer name from the hash when clicked again:
     TypeError: Cannot read property 'documentElement' of undefined

[jywarren]

I removed redundant extra cypress run but still look at this from before I did: https://github.com/publiclab/leaflet-environmental-layers/runs/1624024928?check_suite_focus=true

[jywarren]

Also... # use the new "ci" command for fastest installs on CI

• npm ci

See https://github.com/cypress-io/github-action/blob/master/.github/workflows/example-basic.yml

This didn't work... I think we need to better configure cypress to get past the undefined takeScreenshot error from the previous commit...

[jywarren]

Seeing this now:

> phantomjs-prebuilt@2.1.16 install /home/runner/work/leaflet-environmental-layers/leaflet-environmental-layers/node_modules/phantomjs-prebuilt
> node install.js

Considering PhantomJS found at /usr/local/bin/phantomjs
Found PhantomJS at /usr/local/bin/phantomjs ...verifying
Writing location.js file
PhantomJS is already installed on PATH at /usr/local/bin/phantomjs

we should try switching Cypress to Headless Chrome instead. The errors are all like this now;
