rules_docker breaks for us after updating to rules_go 0.25.0, though this patch fixes it for us:

bazelbuild/rules_docker#1700

The problem is that in our setup, go_register_toolchains() gets called more than once. Simply passing the version isn't a
solution, since after the first call an sdk rule becomes available and then we hit:

go_register_toolchains: version set after go sdk rule declared

Would it be ok to have go_register_toolchains() return gracefully when an sdk is available do to a previous call instead of failing here:
