BRANCH_UNKNOWN in commit message when repository have submodules

[Discoverivan]

What happened?

When generating a commit description in a Git repository with submodules, the placeholder {BRANCH_NAME} is incorrectly replaced with "BRANCH_UNKNOWN." This issue occurs even when there are staging changes from only one submodule. The expected behavior is for the plugin to populate {BRANCH_NAME} with the full name(s) of the branch(es) affected by the staged changes.
