New stable versions aren't created without a reinstall

Following the standard documentation and creating a worktree results in a setup where "stable31.local" is not accessible.

There don't seem to be any differences from the logs produced by turning on stable30, so there is no logged error I can see.

log.txt

How to reproduce:

• Setup nextcloud-docker-dev
• Have a new stable version come out
• Clone the new stable version and set up a worktree
• Run docker compose up stable[x]
• stable[x].local is not accessible on localhost. It only becomes accessible by doing a complete reinstall with bootstrap.sh

Inizia con bootstrap.sh e con la configurazione docker-compose descritta nei passaggi per riprodurre il problema, quindi confronta il log.txt fornito con i log di stable30. Verifica che il nuovo worktree stable possa essere avviato con docker compose up stable[x] e che stable[x].local sia accessibile senza una reinstallazione completa.
