Submodules in Templates Aren't Added to Generated Repositories

[vingenuity]

Description

If you create a template repository containing a submodule, any repositories created from that template do not have the submodule added to it. Specifically, while the ".gitmodules" file is added to the created repository, the submodule object for the folder does not. This means that calls to git submodule init or similar will not work.

My expectation would be that the created repository from the template would contain either a copy of the submodule within it, or a newly generated submodule object. This would allow the cloning developer to use git clone --recurse-submodules to fully create the repository in one go.

I have created an example repository on the Gitea demo site here: https://demo.gitea.com/Vingenuity/submodule-templated-repository demonstrating this issue.

NOTE: This is a different issue from #10316, which is about templates of templates.
