What does this MR do and why?

Currently, when PDM is scanning and reporting code quality reports, it doesn't show the gutter icons in the changes view for Ultimate customers. This is due to the fact, that the location paths have ./ prefixed, which doesn't work according to docs.

How to set up and validate locally

1. Override the pmd-format with the changed script
2. Pushing changes to .java files
3. Be able to see ./ stripped from the paths in the code quality report JSON
4. Be able to see gutter icons in code changes view
