Add check for frozen CHANGELOG.md sections

[koppor]

This uses clparse to detect updates to sections of CHANGELOG.md of released versions. This happens if PRs are longer-lasting than releases.

It implements the suggestion of NiclasvanEyk/keepac#20 (comment)

This PR cannot use heylogs, because nbbrd/heylogs#146 is not merged (and thus the functionality is not available).

Mandatory checks

• Change in CHANGELOG.md described in a way that is understandable for the average user (if applicable)
• Tests created for changes (if applicable)
• Manually tested changed features in running JabRef (always required)
• Screenshots added in PR description (for UI changes)
• Checked developer's documentation: Is the information available and up to date? If not, I outlined it in this pull request.
• Checked documentation: Is the information available and up to date? If not, I created an issue at https://github.com/JabRef/user-documentation/issues or, even better, I submitted a pull request to the documentation repository.

[github-actions]

While the PR was in progress, JabRef released a new version. You have to merge upstream/main and move your entry in CHANGELOG.md to section ## [Unreleased].

It might also be that another CHANGELOG.md issue arose. You can check the detailed error output at the tab "Checks", section "Tests" (on the left), subsection "CHANGELOG.md".

Blocked by marcaddeo/clparse#22

[koppor]

• I switched away from crparse because of Support non-semVer colindean/keepachangelog-parser-java#17
• I switched to heylogs, because of Enable checking git diffs for modifying "frozen" areas nbbrd/heylogs#146.

WTF

I don't get it. Why is the commit id of the checkout branch differently than the commit id which kicked-off the workflow?
