Techdocs allow ignoring folders for dependencies

There is an issue that in storm-121 vendor modules are being linted/checked. These cause the CI to fail because there are issues that are detected.

Since we do not modify the code in the vendor directory, could we just allow ignoring it?

This happened due to a push by @dependabot that added markdown files.

(Although I believe we are moving against vendoring.)

FYI I was able to get around this by just pushing to main. The image will run a diff against the main branch so when it runs in main there is effectively no diff.
