chore: Update qis-compiler snapshots

[aborgna-q]

Looks like #1230 changed the snapshots, but my local wheel cache didn't update.

This PR includes some fixes:

• Update the pytest snapshots of qis-compiler, with the changes arising from fix: BorrowArray discard handler allows elements to be borrowed hugr#2666 and published in hugr 0.23.4.
• Ensures that the required CI checks fail if tests-qis-compiler fails. (And makes sure we don't omit new requirements again).
• Adds update-snapshots-py to the justfile
