Merge bitcoin/bitcoin#24573: Update signapple for platform identifier fix

3c74f775ac Update signapple for platform identifier fix (Andrew Chow)

Pull request description:

  Apparently #23134 is caused by the platform identifier field being set to the incorrect value in our code signatures. The problem has been resolved in signapple, and so guix should point to the latest commit containing the fix.

  I suppose guix does not strictly need to have this; only the macOS code signer will need to have the fix.

  Fixes #23134
