"Supports Folia" can be selected regardless of what the plugin actually supports.

Is your feature request related to a problem?

"Supports Folia" is a completely user-determined tag which can be selected regardless of platform, meaning a velocity or waterfall only plugin could specify that it supports Folia when it doesn't.

Describe the solution you'd like.

Folia support is automatically detected by checking if there is a paper-plugin.yml file with folia-supported: true specified.

Describe alternatives you've considered.

Alternative is that it stays as is, which allows a project to mark "Supports Folia" misleadingly.

One possible consideration: what if a project has two release channels: one which supports folia, and one which does not?
