Rollup merge of #101644 - Timmmm:file_permissions_docs, r=thomcc
Document surprising and dangerous fs::Permissions behaviour on Unix

This documents the very surprising behaviour that `set_readonly(false)` will make a file *world writable* on Unix. I would go so far as to say that this function should be deprecated on Unix, or maybe even entirely. But documenting the bad behaviour is a good first step.

Fixes #74895
