fix(job_queue): Handle Clippy CLI arguments in fix message

fixes #16637

Clippy lints can be enabled via the command line via `cargo clippy -- -Wclippy::lint`, and these need to be included in the `cargo fix` command for the emitting lints to actually be fixed.
Thus, add them to the "run `..` to apply .. suggestions" message.
