8b47a032 - Fix: warn unused ignores when not all specified error codes are used (#11178)

Fix: warn unused ignores when not all specified error codes are used (#11178) Fixes #11157 For --warn-unused-ignored, currently Errors.used_ignored_lines keeps track of only the line numbers without error codes when errors appears on the line with # type: ignore or # type: ignore[...]. This PR changes used_ignored_lines so that it also keeps track of error codes and that information used in generate_unused_ignore_errors to show an error message like unused "type: ignore[attr-defined]" comment.
