feat: add support for running dokken in a container

[ThatsMrTalbot]

Description

When kitchen-dokken is run inside docker itself with the socket mounted in it fails for a number of reasons:

• Kitchen dokken will write files within $HOME/.dokken within the container, then attempt to bind bind that into the container being converged. Because bind mounts mount files/folders from the host this will cause failure.
• If the docker instance is a docker-desktop instance (for example Docker for Mac) then the transport will resolve the incorrect address for the ssh connection

This change causes dokken to detect when it is run inside docker, and if it is it will aways use a data container. It will also connect to the data container using the internal "host.docker.internal" address if it detects the docker instance it is running is is a docker-desktop instance.

• _feat!_:, or fix!:, refactor!:, etc., which represent a breaking change (indicated by the !) and will result in a major version change.

If you have not included a conventional commit message this can be fixed on merge.

LGTM! Can you rebase on main, please? Looks like we've got some linting errors. But happy to merge when ready

[ThatsMrTalbot]

I've rebased off main and fixed the linting issues that "bundle exec rake style" gave me, happy to fix up anything else that the workflow throws up

[ThatsMrTalbot]

@damacus Would you be able to give this a look?

[damacus]

Oh you know what. This might fix some of the other new MacOS bugs I've seen with a new docker desktop install (non-root installed)

[ThatsMrTalbot]

Potentially, these code changes only really change the behaviour if it dokken is running inside a container, aside from the change to the "docker_for_mac_or_win" function, which I did because all recent versions of docker desktop use the new name so the function was broken.
