Merge #7389

7389: Wrap up `bundle cache` migration to current `bundle package` r=indirect a=deivid-rodriguez

### What was the end-user problem that led to this PR?

The problem was that after https://github.com/bundler/bundler/pull/7249, we added the current `bundle package` functionality to the current `bundle cache` command, so that these commands are now aliases of each other.

The initial plan was to do this in a more careful manner but we concluded that this was only _adding_ functionality to `bundle cache`, so not backwards incompatible.

We still need to wrap up the original plan, where `bundle cache` is the preferred command.

### What is your fix for the problem, implemented in this PR?

My fix is to migrate docs, tests and help text to use `bundle cache`, and to remove duplicated specs for `bundle cache` and `bundle package`, since they are testing the exact same code.
