Automatically generate collection deprecation changelog entries from metadata

[felixfontein]

Use ansible-community/antsibull-build#623 to automatically generate collection deprecation changelog entries from metadata.

I should say the output looks OK.

BTW do you want to merge this eventually or is this only meant as an example how it would look like?

I'd merge it together with ansible-community/antsibull-build#623, so that re-generating the changelogs (for example when the next release happens) doesn't result in changes of older entries.

[felixfontein]

I updated the PR to the latest version of ansible-community/antsibull-build#623 and this repo.

[felixfontein]

#459 will allow to also generate the removal changelog fragments automatically.

[mariolenz]

Quite a lot of changes so it's hard to be sure, but I should say this LGTM now.

[felixfontein]

I'd like to regenerate the changelog (and docsite) once more once #464 is merged, to see whether the markup formatting works.

[mariolenz]

Makes sense. Better test this and make make sure.

[felixfontein]

(With the latest changes from ansible-community/antsibull-build#623 and with #464 merged, the generated changelogs will look exactly as they already do. All changes only affect entries in versions not yet released. See ansible-community/antsibull-build#623 (comment) for how the result looks like for 11.0.0a2.)

[felixfontein]

I'll keep this marked as draft until ansible-community/antsibull-build#623 has been merged, then I will merge the latest version of this.

The CI failure is unrelated.
