Unable to recursively init submodules

[Atemu]

After cloning a repository with submodules, it is my understanding that in order to populate all submodules correctly, you must run git submodule update --init --recursive. However, it is not possible to run this command using magit's submodule transient command because the "Update" action does not allow the --init flag and the "Populate" action does not allow the --recursive flag.

Magit 20240320.2336 [>= 3.3.0.50-git], Transient 0.6.0, Git 2.44.0, Emacs 29.3, gnu/linux

magit-submodule-populate should probably accept the --recursive argument. I'll have to think about it and setup a flock of testing repositories.
