typing.Union and astral-sh/ty

In my searches of pandas-stubs, this is the only instance of typing.Union.

Lines 518 to 519 in bf1221e

There are some commented-out uses.

"ty is in preview"

Warning

ty is in preview and is not ready for production use.

We're working hard to make ty stable and feature-complete, but until then, expect to encounter bugs,
missing features, and fatal errors.

https://github.com/astral-sh/ty/blob/e663c524c2f20874b31ec971b91f1e58b7b68d88/README.md?plain=1#L9C1-L14C38

Perhaps change how ty is applied to pandas-stubs instead of changing how pandas-stubs works

It's a lot easier to parse predictable, standardized code, you know?
