refactor: update to use new community ami account

Updates to the project to start using the new CNCF owned AWS account
for publishing AMIs. The code has had the old VMWare account removed
and the new account ID added. Additionally the docs have been updated
including clarifying that the public AMIs should only be used for
non-production usage.
