[Feature Request] Update schedule default values

[cretz]

Describe the solution you'd like

Per temporalio/api#308,

sdk-python/temporalio/client.py

Line 3579 in 3796ec3

catchup_window: timedelta = timedelta(minutes=1)

should now be 1 year. Also, consider if we can have defaults be server-side defaults instead of client-side (changes types to make it seem like this value is optional when it's not). Will discuss with team.

For now it was decided to just change this default value to match server default
