Marking packages commands as deprecated

[pokearu]

Issue https://github.com/aws/eks-anywhere-internal/issues/2270

Description of changes:
As described in the issue we want to mark packages commands as deprecated. For release v0.20.0 the commands are still present and in the next release we would remove the commands themselves.

Documentation added/planned:
Will update the docs and call out that these commands are not supported.
