The submodule repo the test set up had the 'topic' branch checked out,
meaning the repo's default branch (HEAD) is the 'topic' branch.

The following tests then pretended to switch between the default branch
and the 'topic' branch. This was papered over by continually adding
commits to the 'topic' branch and checking if the submodule gets updated
to this new commit.

Return the submodule repo to the 'main' branch after setup so we can
actually test the switching behavior.

Nicely spotted.

And it is good that this variable is used to prepare the test for
both kinds of CI runs that use 'main' or 'master' as the default
branch.
