Merge 38cd156730 into 0c366fd6a8

Setting a submodule as `update = none` is a common way to make cargo
skip the submodule. Unfortunately this makes `actions/checkout` skip
the submodule too, even if it's configured to fetch submodules.

This patch adds an option that is a default in git but causes the
submodules to be available even if skipped otherwise.
