David Peter e8e8180888 [ty] Implicit type aliases: Add support for typing.Union (#21363)
## Summary

Add support for `typing.Union` in implicit type aliases / in value
position.

## Typing conformance tests

Two new tests are passing

## Ecosystem impact

* The 2k new `invalid-key` diagnostics on pydantic are caused by
https://github.com/astral-sh/ty/issues/1479#issuecomment-3513854645.
* Everything else I've checked is either a known limitation (often
related to type narrowing, because union types are often narrowed down
to a subset of options), or a true positive.

## Test Plan
