GLSP-1067: Ensure proper bundling of workflow editor example (#117)

Update maven build to temporarily remove the .gitignore file for diagram
resourced during build. This ensures that tycho properly includes the
resources in the workflow editor plugin for the p2 update site.

Also fix broken codeql workflow
