feat: Add support for team type field

[munlicode]

Adds type field to Team struct and updates tests for listing and getting team(s).

Note: I updated test to use assertNoDiff, because it was printing pointers when TestCopilotService_ListCopilotSeats was failing. Since it is not really helpful for debugging, I changed it to print difference instead of just comparing if it is equal.

Resolves #4033

Since the API also supports "enterprise", would it make sense to add a test case covering that value as well?

That's optional (since marshaling/unmarshaling is already covered by your previous changes) but feel free to add if you wish for documentation purposes. It's your call.
