[SPARK-47202][PYTHON] Fix typo breaking datetimes with tzinfo

This PR fixes a bug caused due to a typo.

This bug is preventing users from having datetime.datetime objects with tzinfo when using the `TimestampType`

No, just a bug fix.

There ought to be CI that lints code and catches these simple errors at the time of opening the PR.

No

Closes #45301 from arzavj/SPARK-47202.
