### What changes were proposed in this pull request?
https://github.com/apache/spark/pull/45409 created a default allow-list of
types for data sources. The intent was to only prevent creation of the two
types that had already been prevented elsewhere in code, but the match
expression matched `StringType`, which is an object representing the default
collation, instead of the `StringType` class, which represents any collation.
This PR fixes the issue.
### Why are the changes needed?
Without it, the previous PR would be a breaking change for data sources that
write StringType with a non-default collation.
### Does this PR introduce _any_ user-facing change?
It reverts the previous unintentional user-facing change.
### How was this patch tested?
Unit test.
### Was this patch authored or co-authored using generative AI tooling?
No.
