Remove Moment from Hotel Server Challenge

[kerimhudson]

Which module(s) and week(s) does this change effect?
Module(s): Node
Week(s): 3

What is the work that needs to be done?

The Hotel Server challenge tells students to utilise the moment library for date checking, however moment is in legacy mode so is not the best library to introduce students to working with dates anymore.

I would maybe suggest moving this to recommend either date-fns or luxon

From what I understand, the students aren't specifically taught this library so it would just be a text change for the recommended library, and not a larger syllabus change.

Why is this work important to do?

To ensure students are working with libraries that are current and up-to-date, and free from security concerns.
