feat: small solutions for running task os:sync-all (#23)

## what
- I ran into an issue where the process would fail if I had not already
cloned the `DEFAULT_MODULES` repos. I added a graceful response where we
git clone the repos for the user.
- I wasn't able to run the sync process because there were existing git
branches from a previous sync. To handle this, I added a global
variable, `DELETE_EXISTING_SYNC_BRANCH`, defaulting to `false` (to keep
existing workflow) so the process conditionally deletes the
`SYNC_BRANCH` and creates a new `SYNC_BRANCH`.

## Summary by CodeRabbit

- **New Features**
- Added an option to control whether existing sync branches are deleted
when syncing repositories.
- **Enhancements**
- Improved handling of repository cloning and branch creation, including
additional logging for clarity.
  - Updated the default module list to include a new module.
