Handle two types of k9s execution and add better diagnostics (apache#…

…37510)

With kind 0.21.0 there was a bug that disallow to use emulation on
ARM after creating Kind cluster, this has been fixed and new images
were released so workaround we implemented in apache#37371 can be removed.
However we should leave the option to use local k9s if installed by
default, and switching to docker when `--use-docker` flas is used.

We also add better diagnostics who might have pulled a buggy
kindest image and telling them how to recover.
