chore: Remove Browserify plugin

[Mrtenz]

Browserify is not actively maintained and we should stop recommending it. With the removal of Browserify from #3322, we can now completely remove Browserify from the repo.

@metamask/snaps-browserify-plugin should be deprecated on NPM after merging this.

I don't quite get the policy changes here, mind explaining?

[Mrtenz]

The dependency graph changed slightly since I removed some Babel packages, which caused other Babel packages to be bumped. I think we now have two versions of @babel/types in the graph, and LavaMoat's algorithm seems to prefer the new one. There are no actual new capabilities added to any package here.
