Fix quick-edit relative path computation when the root folder name appears multiple times in a path

[dario-piotrowicz]

Thanks a lot @WalshyDev, @petebacondarwin and @penalosa for working on digging into this with me 🫶 🙏

Fixes internal issue 55655

Previously, the logic assumed the root folder appeared exactly once in the path. When the root folder name appeared more than once, file modifications were not correctly detected.

For example, if the root folder is my-worker, a path like /my-worker/my-worker/util.js would incorrectly return / instead of /my-worker/util.js.

• Tests
  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
    - I've built the quick edit locally
    - run it locally
    - linked it to the local staging dashboard
    - checked that now the bug we encountered when saving files is no longer present
  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: bugfix
