Bump type checker versions in conformance tests.

rchen152 · rchen152 · commit ac7de0e85a8d · 2026-05-21T16:10:25.000-07:00
As far as I can tell, nothing significant has changed conformance-wise,
but several type checkers have new versions, so we might as well update.

Updated mypy v1.20.2 -&gt; v2.1.0
Updated pyrefly v0.63.1 -&gt; v1.0.0
Updated ty v0.0.35 -&gt; v0.0.38
Updated zuban v0.7.1 -&gt; v0.7.2
