Unrolled build for rust-lang#135145

Rollup merge of rust-lang#135145 - kpreid:unnameable, r=compiler-errors

Mention `unnameable_types` in `unreachable_pub` documentation.

This link makes sense because someone who wishes to avoid unusable `pub` is likely, but not guaranteed, to be interested in avoiding unnameable types.

Also fixed some grammar problems I noticed in the area.

Fixes rust-lang#116604.
