feat: Automated commits to NangoHQ/nango for use-cases.json and flows.yaml

[nalanj]

Describe your changes

Update flow sync script to also generate and sync use-cases.json. Also updates commit message to add some newlines to it.

I'll only have this run on main and fix the push target to only be master on the nango repo once this is reviewed and approved.

Checklist before requesting a review (skip if just adding/editing APIs & templates)

• I added tests, otherwise the reason is:
• External API requests have retries
• Pagination is used where appropriate
• The built in nango.paginate call is used instead of a while (true) loop
• Third party requests are NOT parallelized (this can cause issues with rate limits)
• If a sync requires metadata the nango.yaml has auto_start: false
• If the sync is a full sync then track_deletes: true is set
• I followed the best practices and guidelines from the Writing Integration Scripts doc

The sync test above is failing because I deleted the branch it was running against. It's easy enough to re-enable but I was trying to keep it from running here.
