CI is broken; also there is no linting for the changelog

[felixfontein]

Currently CI seems to be broken and should be fixed.

Also it looks like changelogs/changelog.yaml is edited manually instead of using changelog fragments, and no linting is run on the results. Running antsibull-changelog lint-changelog-yaml changelogs/changelog.yaml produces a list of problems:

changelogs/changelog.yaml:0:0: 'releases' -> '4.0.0' -> 'changes': section "minor_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.1.0' -> 'changes': section "major_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.3.0' -> 'changes': section "major_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.4.0' -> 'changes': section "major_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.4.1' -> 'changes': section "major_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.5.0' -> 'changes': section "major_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.5.1' -> 'changes': section "bugfixes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.5.1' -> 'release_date' is expected to be <class 'str'>, but got None
changelogs/changelog.yaml:0:0: 'releases' -> '5.6.0' -> 'release_date' is expected to be <class 'str'>, but got None
changelogs/changelog.yaml:0:0: 'releases' -> '5.7.0' -> 'changes': (WARNING/2) Inline emphasis start-string without end-string.
changelogs/changelog.yaml:0:0: 'releases' -> '5.7.0' -> 'changes': section "major_changes" list items must be type str not dict
changelogs/changelog.yaml:0:0: 'releases' -> '5.7.0' -> 'release_date' is expected to be <class 'str'>, but got None

If you manually edit changelogs/changelog.yaml, please carefully study the specifications (https://ansible.readthedocs.io/projects/antsibull-changelog/changelog.yaml-format/) and use the linter to verify that everything looks good from a technical point of view.
