Managing compatible versions for a plugin

[argenos]

This is something I was looking for today. Adding information for managing versions, quoting Licat:

Say you were on 1.0.0 which is compatible with 0.10.0+, and now you push out 1.0.1 that's only compatible with Obsidian 0.10.2+.
You should put in version=1.0.1 and minAppVersion=0.10.2 in your manifest.json, then add "1.0.0": "0.10.0" to your versions.json
...
if you had anything that was compatible with 0.9.7 in your versions.json, it would use the latest
so let's say you had "0.0.3": "0.9.10", "0.0.2": "0.9.4", "0.0.1": "0.8.1", then it will pick 0.0.2 for app version 0.9.7

What is the general workflow for contributions? Should I make a PR? To which file/section would it make sense to add this?
