github: Revert "github: Remove kata-deploy-test action"

This partially reverts commit 1cce930071.

As mentioned in #1635, the malformed yaml wouldn't allow us to actually
test changes that were supposed to be test by this action.

So, this is now reverted and adapted accordingly.

Main differences from what we had before:
* As it tests kata-deploy itself, not the statically built binaries,
  let's just use the binaries from 2.0.0 release;
* Adapt download and deploy location to the
  `kata-containers/kata-containers` repo, as the original action was
  based on 1.x repos;

Fixes: #1640
