Auto merge of #94105 - 5225225:destabilise-entry-insert, r=Mark-Simulacrum

Destabilise entry_insert

See: https://github.com/rust-lang/rust/pull/90345

I didn't revert the rename that was done in that PR, I left it as `entry_insert`.

Additionally, before that PR, `VacantEntry::insert_entry` seemingly had no stability attribute on it? I kept the attribute, just made it an unstable one, same as the one on `Entry`.

There didn't seem to be any mention of this in the RELEASES.md, so I don't think there's anything for me to do other than this?
