Default umbrel-dev to host networking in WSL

On Windows, the dev environment works best with WSL, but doing so adds
one more layer of encapsulation. To simplify the process, add a sensible
default that undoes one layer by using Docker host networking within
WSL, so Umbrel OS is passed through to the WSL interface with no need to
publish particular ports within the Docker container.

This behavior can be overridden by setting `UMBREL_DEV_OPTIONS` on the
command line, which is then preferred over the default.

Also adds a new `npm run recreate` command to allow recreating existing
instances with the latest WSL network changes applied.

 natively works on Linux and can be done with OrbStack on macOS. On Windows this should work with WSL 2.
