Update the EBF tutorial

[medyagh]

our ebf tutorial is ancient and has deadlinks:
do we still need to do these extra steps such as using a custom ISO and linux headers?
did we add the ebf to minikube ISO ?

@eiffel-fl do you know if our old tutorial ^^ can we remove those lines about cutsom iso ?

@spowelljr pointed out this PR #12707 that might mean we no longer need the custom ISO but do we need to also remove the lines about custom header?

ou will need to download and extract necessary kernel headers within minikube:

```shell
minikube ssh -- curl -Lo /tmp/kernel-headers-linux-4.19.94.tar.lz4 https://storage.googleapis.com/minikube-kernel-headers/kernel-headers-linux-4.19.94.tar.lz4

minikube ssh -- sudo mkdir -p /lib/modules/4.19.94/build

minikube ssh -- sudo tar -I lz4 -C /lib/modules/4.19.94/build -xvf /tmp/kernel-headers-linux-4.19.94.tar.lz4

minikube ssh -- rm /tmp/kernel-headers-linux-4.19.94.tar.lz4

I tried to run it on my qemu on macos but seems like we also need to tell ppl this is not supported for arm64

Why not use the vfkit driver? We don't support yet rosetta, but with small change we can add rosetta support to the vfkit.

I'm using rosetta with lima to run clusters mixing arm64 and amd64 images and it works beautifully.

Hi!

The custom ISO was mainly needed for test purpose while I added the CONFIG_BPF to Minikube kernel in #14316.
Since this PR was merged, we do not need to use this flag, so I guess you can remove anything about it in the documentation.

Best regards.
