7388: Fix help with command aliases r=deivid-rodriguez a=deivid-rodriguez

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

The problem was that the output of `bundle help install` and `bundle install --help` was inconstent with `bundle i --help`, and the same issue with all of the other command aliases.

### What was your diagnosis of the problem?

My diagnosis was that the command reformatting so that `bundle <cmd> --help` "redirects" to `bundle help <cmd>` was ignoring command aliases.

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

My fix is to make this logic aware of command aliases.
