Feature: file-specificity on lint.pyupgrade.keep-runtime-typing

[tlambert03]

Not sure if I missed an already-possible feature, but I often find myself working in libraries that need keep-runtime-typing = True for only a select few files. It would be convenient, in those cases, to enforce the rule for a subset of files with something like:

[tool.ruff.lint.pyupgrade]
keep-runtime-typing-files = ["src/subfolder/*.py"]

this is not currently possible, right?

It's not currently possible but we do want to support it, probably in a more general way like #7696. I'm gonna merge into that issue!
