Add OrbStack instructions

[jorgemoralespou]

Describe the bug

When creating a cluster in OrbStack, we run into the same issue as with Colima, so instructions need to detail this:

In quick-start-guide.yaml doc we need to update:

In case you are using [Colima](https://github.com/abiosoft/colima) or [OrbStack](https://orbstack.dev/), you need to add the following lines to the educates configuration file:

$ educates local config edit
localKindCluster:
  listenAddress: 0.0.0.0

It seems that if both Orbstack and Docker are installed, then the Docker context mechanism does not work for docker golang library, so that one will need to set the DOCKER_HOST to the Orbstack socket which can be fetched via docker context inspect orbstack -f json | jq -r ".[0].Endpoints.docker.Host"

Because of this moby/moby issue (moby/moby#42650) it seems that in order to use the current selected context, and not the client.NewClientWithOpts(client.FromEnv) but rather create an Opts struct with the values from the current context, one would need to use the Docker cli (or some logic from it), so it seems complicated :-(
