Basic Ruby Loops lesson: Recommend skipping recursion in assignment

[jonathanmeneses]

Because

The Launch School curriculum in the Loops lesson of the Ruby Course discusses recursion. TOP intentionally does not discuss recursion until the "A Bit of Computer Science" section in the Ruby Course.

As it stands, if learners were to fully read the Loops lesson assigned, they may deep dive into recursive methods earlier than TOP intends (we can equate this to a rabbit hole).

This PR

• Adds a note in the assignment to review the Loops lesson that encourages the learner to ignore recursion until it appears later in TOP.
