Clarify documentation of strip_whitespace

Initial Checks

• I confirm that I'm using Pydantic V2

Description

The doc for StringConstraints strip_whitespace says "Whether to strip whitespace from the string." - to me that's unclear if it's stripping all whitespace or only leading/trailing (it's the latter I think).

I think it'd be clearer if it said "Whether to remove leading and trailing whitespace." which I think is the actual behaviour, and aligns with the doc for constr - https://docs.pydantic.dev/latest/api/types/#pydantic.types.constr

https://docs.pydantic.dev/latest/api/types/#pydantic.types.StringConstraints

Maybe this unit test should be updated to include a space inside of ABC to assert on that behaviour? 8bc104f#diff-bd467a363c9f155a2e6a7716aeca0c351089135a53d09a66138cea4f16506ebdR5574
