Rollup merge of #154188 - rperier:diagnostic_on_move_point_to_the_tracking_issue, r=JonathanBrouwer

Update the tracking issue for #[diagnostic::on_move]

PR rust-lang/rust#150935 has been merged and then I have opened the tracking issue (whoops ?). So this update `compiler/rustc_feature/src/unstable.rs` to point to the right tracking issue.

This is related to the tracking issue rust-lang/rust#154181
