[mod] update_engine_descriptions.py - revision of the script (#6309)

* [mod] update_engine_descriptions.py - revision of the script (#6309)

The script was a bit outdated, type hints were missing, and the strings were
converted to double quotation marks

The `descriptions.items()` are sorted to avoid assigning the references to
seen_descriptions randomly (should reduce unnecessary diffs in the future).
