Backport small changes from the 1.20.4 branch

- Add support for version overrides/exclusions in our dependency check.
   Sometimes mod loaders use different versions to vanilla, and we need
   some way to handle that.

 - Rescan wired network connections on the tick after invalidation,
   rather than when invalidated.

 - Convert some constant lambdas to static method references. Lambdas
   don't allocate if they don't capture variables, so this has the same
   performance and is a little less ugly.

 - Small code-style/formatting changes.
