lint: markdown check linting build outputs #31044
Description
Running the linter locally I see this output:
DOCKER_BUILDKIT=1 docker build -t bitcoin-linter --file "./ci/lint_imagefile" ./ && docker run --rm -v $(pwd):/bitcoin -it bitcoin-linter
<snip>
One or more markdown links are broken.
Relative links are preferred (but not required) as jumping to file works natively within Emacs.
Markdown link errors found:

GOOD
<snip>The output is somewhat confusing because it seems to simultaneously claim that things are broken, but that all checks passed? In any case, the linter should not be running on files that are not our source code, or is gitignored. i.e here it's running on Qt build outputs, but it shouldn't be linting anything under depends/work/, depends/built/, depends/${host}/ etc.
