dokkaBuildProvenanceGitRoot
Root of the git repository that contains this module's sources. Used together with projectRoot to compute the path prefix from git root to project root so that GitHub blob URLs in check-results tables point to the correct location (e.g. models/stig-project/activities/...).
Conventioned from the matching com.stigway.engine.scm.GitRepoInfo.root resolved via com.stigway.engine.scm.resolveModuleRepoInfo. When unset the prefix is assumed to be empty (git root == project root).
