Include relevant changelog on Release page

Description of the new feature or improvement

It would be convenient not only see build number, but relevant changelog parts, e.g.:

build 6331

changelog:

--------------------------------------------------------------------------------
drkns 2024-05-06 12:34:28+01:00 - build 6331

1. Refactoring.

LuaMacro\changelog:

shmuel 2024-05-06 11:34:46+03:00 - build 831

1. mf.eval(S,2): invalid area in 'S' is treated as a part of key

2. mf.eval(S,2): a leading slash in 'S' indicates that no area is specified

Alternatively: list of commits messages since last build, e.g.:

build 6331

• Add new netbox files to the installer @alabuzhev May 5, 2024
• mf.eval(S,2): invalid area in 'S' is treated as a part of key @shmuz May 6, 2024
• Refactoring @alabuzhev May 6, 2024

Alternatively: link to github compare, e.g.:

build 6331

builds/3.0.6330...builds/3.0.6331

Proposed technical implementation details (optional)

To get news from changelog we need to compare old size vs new size, and output only diff.

It could be improved indeed.
We probably could steal a few ideas from other projects, e.g. include merged PRs and contributors like in michaellukashov/Far-NetBox.

But I hate this yaml nonsense with all my heart, so please don't count on me, it might take forever.
PRs are welcome.

e.g. include merged PRs

That could be useful if only this project would PR-driven, which is not currently in case.
So better stick to commits msgs reciting.
