* Document support for `@copilot` in `gh [pr|issue] edit --add-assignee` and `--remove-assignee`
Following up on #10991, this updates the help text for
`issue edit` and `pr edit`'s `--add-assignee` and
`--remove-assignee` options to mention that you can use
`@copilot`.
This is already mentioned in the command-level help text, but
not at the argument level, whereas the `@me` macro is.
