Chore: Automatic YAML changelog generation

[ShizCalev]

Missed the meeting, but it's definitely possible for YMAL changelogs to be automatically generated from PR's. We have it implemented over at https://github.com/tgstation/tgstation Unfortunately I'm not too familiar with setting up git workflows, so someone else would have to implement it.

How we have it set up:

1. User opens a PR, the PR template has the changelog template already, which the user fills out themselves

Example: (Words after the first 🆑 tag are the name used for the changelog, otherwise they're anonymous.)

2. On PR merge, a YMAL file gets generated in html/changelogs If a user makes a mistake & forgets something, they can manually generate a changelog YMAL file in this folder as well.

3. All changelogs then get compiled into a larger yml for the entire month: https://github.com/tgstation/tgstation/blob/master/html/changelogs/archive/2025-03.yml

Optional improvement: https://github.com/tgstation/tgstation/tree/master/tools/pull_requests/autoLabel.js https://github.com/tgstation/tgstation/tree/master/tools/pull_requests/autoLabelConfig.js automatically labels PR's based off their changelog

I will investigate, maybe the workflow you described is not exactly what we need here but I can look at the general idea.
