Submodules don't run LFS checkout

[yottapanda]

Say I have repo A and repo B. Repo A includes repo B as a submodule. Repo B has an lfs-stored png.

Using the default clone behaviour, the LFS PNG in repo B is not checked out when running a workflow on repo A.

+ git init -b main
Initialized empty Git repository in /woodpecker/src/git.example.com/keval/a/.git/

+ git lfs fetch
fetch: Fetching reference refs/heads/main
+ git lfs checkout

assets/b/lfs.png is still an LFS text file

The following 2 commands fix the problem:

git submodule foreach git lfs pull
git submodule foreach git lfs checkout

But this could probably be tuned
