Fix connections create-oauth validation errors

[shihanpan]

• Add type=int to --parent-id to ensure proper conversion from CLI string to integer
• Add required=True to --external-id since it's not optional in the function signature

Fixes validation errors:

• parent_id: Input should be a valid integer [type=int_type, input_value='92', input_type=str]
• external_id: Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]
