Changes to build_loop.yml and update.yml:

build_loop.yml:
-Remove sync action from build_loop.yml
-build on schedule on the 1th every month for a predictable build schedule well within the 90 day TestFlight limit. The time of day should be chosen as a time where ongoing changes are unlikely during releases (nighttime).
-rename env TARGET_BRANCH to BUILD_BRANCH
- use current branch as BUILD_BRANCH for easy switching to building main or dev (manually insert alternative branch names as needed)

update.yml:
- check for updates every day
- use current branch name for UPSTREAM_BRANCH and TARGET_BRANCH, to easily switch between dev and main by changing default branch, without any code changes.
- do not run the upstream sync action on the upstream LoopKit repository
- time_elapsed: 50 days for keepalive action
