Emit a warning when a plugin depends on a recent weekly

[daniel-beck]

What feature do you want to see added?

(TBH I don't know if it exists, but #2665 was hosted just two days ago and currently depends on 2.359.)

A warning should be emitted in the hosting check when a plugin depends on a recent weekly release. While there are some (limited) reasons this is needed, often it seems to be developers not understanding how this particular dependency works and unnecessarily limit who can use the plugin. https://www.jenkins.io/doc/developer/plugin-development/choosing-jenkins-baseline/ should be linked as documentation.

(And dependencies on older weekly releases should probably be pointed out too and that they should just be LTS, but for a different reason.)
