Guidance on display of external URLs in lessons

[ostephens]

Before Library Carpentry lessons formally joined the Carpentries, we had some discussion about the display of URLs in lessons (see https://github.com/data-lessons/library-openrefine-DEPRECATED/issues/54)

tl/dr; should we include full URLs in the lesson visible to the users so they can be read both on screen and in print outs, or should they be done as hyperlinks with sensible link text instead of the full URL displayed

Guidance on this in the style guide would be appreciated

Tagging @serahrono as I think this falls into accessibility work she is doing.

I believe URLs are automatically shown in full when you print lesson content. (At least in the old infrastructure they were.)

So the "lemma" on links in the style guide applies, in my opinion: use meaningful text as link text, not URLs.
