validate and document how to debug on WSL2 windows

I'm not in a rush to get this working on windows native, but to how to:

1. get k3d running
2. figure out network routing
3. create commands for it.

will update, it's actually fairly simple:

in order for the webhook to be forwarded, you need to open up port 3000. (maybe port 443 too).

should do a full walk through of wsl2 from scratch with docker desktop.

Do not run Docker desktop, deploy dockerd directly in wsl2, docker desktop's WSL2 mode does not allow bridge networks to be easily accessible from wsl2 or windows. The metallb stuff will just not run well.
