[ty] Run mypy_primer and typing-conformance workflows on fewer PRs (#22096) ## Summary Fixes https://github.com/astral-sh/ty/issues/2090. Quoting my rationale from that issue: > A PR that only touches code in [one of these crates] should never have any impact on memory usage or diagnostics produced. And the comments from the bot just lead to additional notifications which is annoying. I _think_ I've got the syntax right here. The [docs](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax) say: > The order that you define paths patterns matters: > > - A matching negative pattern (prefixed with !) after a positive match will exclude the path. > - A matching positive pattern after a negative match will include the path again. ## Test Plan No idea? Merge it and see?
