setup-wsl + actions/checkout ?

[MarximusMaximus]

I'm not sure if this issue is for setup-wsl or actions/checkout.

I've run setup-wsl, and that worked. But I'm trying to use actions/checkout now to checkout the repo and it fails in "neat" ways.

1. it will default to using windows git and muck up all line endings
   1.a)

• add git and git-lfs additional packages to WSL
• write a git.cmd override that is wsl git %* so that we use WSL's git
• setup WSLENV so that GITHUB_* and RUNNER_* env vars get passed down to WSL
• basic git commands now work and use WSL's git!

2. actions/checkout does indeed use wsl's git, but uses all windows paths (presumably b/c it's running via node in win32)
   2.a) have git.cmd use ${{ steps.setup-wsl.outputs.wsl-shell-wrapper-path }} git %* instead, but that just yields:

Invalid arguments 
Usage: wsl-sh [-u <user>] <script file a.k.a. {0}> 

2.b) tried to override node in the same way as git, but it doesn't work (it either still uses the WIN32 node, not WSL node; or is using the WIN32 env vars and not the WSL env vars)

Any ideas would be greatly appreciated.
