Deduplicate findReadmeFile() (#22177)
This code was copy-pasted at some point. Revisit it to reunify it. ~~Doing that then encouraged simplifying the types of a couple of related functions.~~ ~~As a follow-up, move two helper functions, `isReadmeFile()` and `isReadmeFileExtension()`, intimately tied to `findReadmeFile()`, in as package-private.~~ Signed-off-by: Nick Guenther <nick.guenther@polymtl.ca>
