Remove 'Remotes' section from DESCRIPTION

[chrismainey]

I think we should remove the remotes section from the description file, because it blocks users in Posit Cloud from downloading any packages. They don't have permissions to install from github in that session (no credentials I assume), and it just errors out. This derails you if any packages are missing in their project. E.g. when using readr to import data, a couple of people were missing it but couldn't install until I showed them to delete the remote section.

@Lextuga007 @tomjemmett , what do you think?

This might be related to another issue #43 on too many package dependencies. Are people on the course using this repository though as they really only need the html rendered slides and the data files:

• html pages
• data files
