"git submodule--helper config" isn't familiar to me, so I did a bit of
digging. It looks like it falls into the category of submodule--helper
subcommmands that exist to expose functionality that's easy to do
in-process, but otherwise inaccessible to git-submodule.sh.
Its last use (I think) was in a6226fd772 (submodule--helper: convert the
bulk of cmd_add() to C, 2021-08-10).

In a few of the test names, we still say 'do X with "submodule--helper

The value of the writeable/unwriteable tests feels quite low to me, but
I am ok to keep them just to be safe.
