Is your feature request related to a problem? Please describe.
When i create a new project for supabase i might need to update or download all functions from supabase and it's super annoying to do that by writing each function name, it would be greate to be able to download all functions
Describe the solution you'd like
If someone used: supabase functions download, it should be able to download all functions, not just one.
Describe alternatives you've considered
i thought about having options like:
supabase functions download --all, but the no-argument option felt better.
