This one is expected to be big as it is ruff's formatter yearly upgrade.

New stable lints

All new violations are autofixable

• PLR1716 (1)
  • STY: autofix for PLR1716 (boolean-chained-comparison) #17616
• FURB188 (6)
  • STY: autofix for FURB188 (slice-to-remove-prefix-or-suffix) (table) #17617
  • STY: semi-manual fix for FURB188 (slice-to-remove-prefix-or-suffix) (io.fits) #17619
  • STY: autofix for FURB188 (slice-to-remove-prefix-or-suffix) (io.votable) #17620
• RUF100 (100)

RUF100 (unused-noqa) violations are probably best resolved only when we upgrade (otherwise we might get errors from ruff 0.8.x ...), but the other two can be addressed in advance. I'll open a couple PRs to that effect now.
