Using `update = none` for submodules breaks git commands

[rosekunkel]

Some git commands don't work correctly if submodules aren't initialized. For example:

$ git clone --recurse-submodules https://github.com/ubolonton/tree-sitter-langs
$ cd tree-sitter-langs
$ git reset --hard
fatal: not a git repository: ../../.git/modules/repos/agda
fatal: could not reset submodule index

This causes problems for tools that operate on git repositories. For example, this package breaks the update tool for Doom Emacs: https://github.com/hlissner/doom-emacs/issues/5064

This should likely be fixed in straight.

[rosekunkel]

The problem isn't related to straight, the Doom Emacs tool uses git commands directly.

The problem isn't related to straight, the Doom Emacs tool uses git commands directly.

For itself, not for package upgrades. So the problem is related to straight.
