chore(tool): add "remove" alias to "tool delete"

[queengooborg]

Summary

This PR adds a remove (and rm) alias to the yarn tool delete command.

Problem

I often accidentally type yarn content remove ... when attempting to remove and redirect a page in MDN content. This is because remove is the more common phrase used in development.

Solution

The solution is simple: to alias the delete command. This will allow the use of remove (or rm), without impacting the workflow of existing users.

How did you test this change?

Just ran yarn tool remove and yarn tool rm and made sure it outputs the same message as yarn tool delete.
