Fix browser build sync and alive behavior (LoopKit#164)

* Fix browser build sync and alive behavior
- Added logic to extend the alive check for the existence of either `alive-main` or `alive-dev` branches.
  - Resolved an issue where unexpected successes were occurring when failures were expected.
  - Implemented a check to determine the existence of the `alive-main` and `alive-dev` branches and create them if they do not exist.

- Introduced a mechanism to identify the current branch being run (either `main` or `dev`).
  - Based on the current branch, the corresponding alive branch (`alive-main` or `alive-dev`) will be used to check for upstream changes.

- Set a new variable `ABORT_SYNC` to `true` when the current branch is neither `dev` nor `main`.
  - The syncing attempt will proceed based on the `ABORT_SYNC` variable status.

- Ensured proper branch synchronization to prevent build inconsistencies and failures

- Addresses issue LoopKit/Loop#2192

- Updates app store connect link for validation error hints to new Apple URL scheme

* 💚 Security Fix
