updates from testing cpp-linter/cpp-linter-action#81

[2bndy5]

This PR is just for testing PR events on the backlogged-updates branch. It is not meant to actually get merged.

It wouldn't hurt to merge this for the submodule and improvements to generating the compilation database on Windows.

I had to disable the database option for the workflow that runs the action with a docker env because it prevents the file annotations from being created.
