Rollup merge of #111756 - Urgau:rename_drop_forget_copy_ref_lints, r=fee1-dead

Rename `{drop,forget}_{copy,ref}` lints to more consistent naming

This PR renames previous uplifted lints in https://github.com/rust-lang/rust/pull/109732 to more consistent naming.

I followed the renaming done [here](https://github.com/rust-lang/rust/issues/53224) and also advocated in this [clippy issue](https://github.com/rust-lang/rust-clippy/issues/2845):
   - `drop_copy` to `dropping_copy_types`
   - `forget_copy` to `forgetting_copy_types`
   - `drop_ref` to `dropping_references`
   - `forget_ref` to `forgetting_references`
