Fix lost form submissions on archives, the unlocked update finish and six more

Update Symfony to 7.4.23 (12 advisories in 8 packages).

- A form can be sent from /beitraege, /kategorie/... and /schlagwort/...;
  it answered 404 before anything was stored or mailed.
- Booleans reach the database as integers, so MySQL in strict mode
  accepts form submissions, task switches and plugin states.
- A stepped form with a required multiple choice shows its message
  instead of stopping on a TypeError.
- The second update step runs under the update lock; a concurrent
  finish no longer rolls a successful update back.
- Accordion entries and gallery images can be selected from the
  editor panel again.
- Category and tag names are escaped in the archive heading.
- Restoring a published page from the bin needs the publisher role.
