feat: Add Minikube documentation

[afbjorklund]

What does this PR do?

This is the documentation for the minikube extension. It is rather similar to the "kind" extension.

Both Kubernetes extensions share a lot of concepts, even though the commands differ slightly.

would be nice if we could merge some items to maybe avoid duplication but can be done as a next thing once it'll be merged.
Need to have the extension in its own repository before merging here

Thanks for the awesome documentation! I only have a few comments.

Also, minikube on all official documentation (github, https://minikube.sigs.k8s.io/docs/) is stylized as lowercase minikube not Minikube.

Unsure of the english on it, but I think minikube should be lowercase on all references? Just a small nitpick. I just remember docs teams sometimes being very specific on whether or not something is capitalized. Like how crc is not Crc and minishift is Minishift, and then microshift is MicroShift. Just a thought

[afbjorklund]

I think it used to be a thing also in minikube, but I'm not sure it actually matters to anyone anymore...

Except for in the logo, perhaps ?

Trying to spell things like CRC or CRI-O seem to always end up failing anyway - so might as well use English.

Thanks for the awesome documentation! I only have a few comments.

Note that since most of this Kubernetes documentation has been duplicated from the Kind-specific section, most of the things being addressed applies also to that original documentation. Maybe they could be merged, in the future?

Example:

-# Configuring Podman for Kind on Windows Subsystem for Linux (WSL)
+# Configuring Podman for Minikube on Windows Subsystem for Linux (WSL)
 
 When you create a Podman machine, Podman creates the machine in rootless mode.
 
-With a Podman machine running on WSL, Kind:
+With a Podman machine running on WSL, Minikube:
 
 - Requires the rootful machine.

@benoitf : thanks, will you add some instructions on how to install the minikube extension ?

https://podman-desktop.io/docs/extensions/install

[benoitf]

@afbjorklund we could replace the placeholder on https://podman-desktop.io/docs/extensions/install being quay.io/fbenoit/my-first-extension by the minikube extension
but we're still missing in extension page the list of ALL extensions, not only featured extensions

[afbjorklund]

I was thinking there needs to be a link from the minikube docs, until the featured (or catalog) is in place

[benoitf]

@afbjorklund yes it does not prevent to have links
