Post Resource Updates

[HeroCC]

Hello! As a plugin author, I'd love the ability to push updates to resources programatically.

For the full context / justification, I'm working on a CI chain for a few of my plugins which builds & runs unit tests. Then I'll manually test, and if things work well, publish the tag as a release on GitHub, which will get picked up by Github Actions and publish to several different places (Maven repos, BukkitDev, and ideally spigotmc.org).

Additionally, it would be great to have an endpoint to update the overview page & other metadata, but that isn't as necessary for my use case.
