chore: Remove old undocumented migrate command (#32114)

This removes the `appsmithctl migrate` command which can migrate an
Appsmith instance from on EC2 instance to another, using SSH. Why are we
removing it?

1. It's not documented on docs.appsmith.com at all.
2. The problem is better solved with a combination of `appsmithctl
backup` and `appsmithctl restore`, with much _more_ flexibility.
