Refactor: Update nightly release workflow to use outputs

This commit refactors the nightly release workflow to use outputs to determine if subsequent jobs should run, instead of relying on environment variables.

- The `checkNightly` job now has an output called `shouldRun` that indicates if there are new commits.
- Subsequent jobs now utilize `needs.checkNightly.outputs.shouldRun` instead of `env.NEW_COMMIT_COUNT` to determine their execution condition.
