GitHub Actions

[derrabus]

This PR ports our CI to GitHub Actions. While Travis still considers if it should boot the VMs for our CI, the run on GH Actions has been completed already.

• This PR includes Bump minimum PHP version to 7.1 #303, so please ignore the first commit when reviewing
• The PHP 8 run fails (as it does on Travis). I'll try to resolve this in Fix CI for php 8 #301.

GH Actions seem to be disabled on this repo. Here's the latest run on my fork: https://github.com/derrabus/polyfill/runs/1298646165

Dunno why they didn't run. Settings tell they are enabled.

IIRC, the workflow files need to be present in the target branch to allow the job to run. A PR adding the CI workflow won't trigger it.

Oh my. Well then, you can click on derrabus:improvement/gh-actions at the top of this page to see the latest run.

The failure on PHP 8 is because it installs PHPUnit 9.3 which is not yet supported by the bridge (I think 5.2-dev supports it but I'm not sure). Travis was forcing SYMFONY_PHPUNIT_VERSION=7.2

PhpUnitBridge 5.2-dev is actually being used. That's why we get PHPUnit 9.3 in the first place.

The listener is the problem. (edit: actually the test listener of the polyfills, not the bridge)

Travis was forcing SYMFONY_PHPUNIT_VERSION=7.2

Yes, but Nicolas' PR removes that already. PHPUnit 7.2 won't work either because it is not compatible with PHP 8.

Thank you @derrabus.
