chore(lint): fix Ruff errors in query_gsquery.py (#5003)

- Add .github/linters/.ruff.toml with line-length 88 to match Black.
  Super Linter's default Ruff config uses 120, so ruff format and Black
  disagreed about the same file. target-version py38 keeps Ruff from
  suggesting changes that need a newer Python than Ubuntu 20.04 has.
- query_gsquery.py: make executable (EXE001), drop the redundant coding
  declaration (UP009) and an empty comment (PLR2044), and catch OSError
  instead of its alias socket.error (UP024).
