Change to GitHub CI

[rikhuijzer]

Fixes #1494

Contributor checklist:

Proposed changes

• Switch from TravisCI to GitHub Actions.

[rikhuijzer]

Documentation works at https://rikhuijzer.github.io/Gadfly2.jl/dev/. It also has a working favicon #1488.

[rikhuijzer]

At this point, this branch seems to obtain the same CI outputs as the Travis configuration on master for the tests and it fixes the build of the documentation, so I removed the "Work-in-progress" part from the title.

LGTM. @Mattriks ?

@rikhuijzer the docs built successfully after #1505 was merged, but they do not seem to have been deployed. is that perhaps because CI failed for julia 1.0? anyway to change github CI to fix it? thanks.

[rikhuijzer]

@bjarthur Hmm, I should have checked the logs earlier. When looking at the GitHub Actions logs for the change to GitHub Workflow merge [1] and the most recent merged PR [2], I see

 ┌ Info: Deployment criteria:
 │ - ✔ ENV["TRAVIS_REPO_SLUG"]="" occurs in repo="github.com/GiovineItalia/Gadfly.jl.git"
 │ - ✘ ENV["TRAVIS_PULL_REQUEST"]="" is "false"

 │ - ✘ ENV["DOCUMENTER_KEY"] exists
 │ - ✔ ENV["TRAVIS_EVENT_TYPE"]="" is not "cron"
 └ Deploying: ✘

So, it seems that DOCUMETER_KEY does not exist. Could you or someone else with the required permissions add this key? See the instructions in [3].

done. but it still didn't deploy:

┌ Info: Deployment criteria:
│ - ✔ ENV["TRAVIS_REPO_SLUG"]="" occurs in repo="github.com/GiovineItalia/Gadfly.jl.git"
│ - ✘ ENV["TRAVIS_PULL_REQUEST"]="" is "false"

└ Deploying: ✘```

[rikhuijzer]

It seems that Documenter still looks for Travis, which isn't the case for the CI repository I made at https://github.com/rikhuijzer/Gadfly2.jl, there it says:

┌ Info: Deployment criteria for deploying devbranch build from GitHub Actions:
│ - ✔ ENV["GITHUB_REPOSITORY"]="rikhuijzer/Gadfly2.jl" occurs in repo="github.com/rikhuijzer/Gadfly2.jl.git"
│ - ✔ ENV["GITHUB_EVENT_NAME"]="push" is "push"
│ - ✔ ENV["GITHUB_REF"] matches devbranch="master"
│ - ✔ ENV["GITHUB_ACTOR"] exists
│ - ✔ ENV["DOCUMENTER_KEY"] exists
└ Deploying: ✔

Lets hope that a newer Documenter version solves it, and if not, go from there.
