CI broken for PRs

[tobil4sk]

The CI does not run properly for PRs, so there's no automatic way of seeing whether a PR's tests are succeeding. It fails at this part of the push job: https://github.com/HaxeFoundation/haxelib/blob/7d1d6b73d7672ceca5d06062773b7cb7905c3316/.github/workflows/ci-dev.yml#L43-L47

I'm guessing the reason it is failing is that the docker token is not available in the PR ci environment which is probably for security reasons.
