fix(git-submodules): take git-tags and git-refs hostRules into account

[Shegox]

Changes

This PR adds support for two extra hostTypes when looking up the defeault branch for git-submodules as well as when updating git-submodules. This allows users to define hostRules independent of the hostType via the already existing rules for git-tags and git-refs used by the same datasources.

I tested this change against a private GitLab instance with a Renovate token for only the "parent" repository and adding an extra hostRule like this to allow for access to the private submodule:

{
 hostRules:[
    {
      hostType: "git-refs",
      matchHost: "gitlab.int",
      username: "oauth2",
      password: "subModuleToken"
    },
    {
      hostType: "git-tags",
      matchHost: "gitlab.int",
      username: "oauth2",
      password: "subModuleToken"
    }
}

@Shegox ready for review/merge?

@rarkins should be ready, although no longer needed in addressing #24077 as I first though, but might be helpful non the less
