LibGuides and AZ: Display descriptions

[maccabeelevine]

Optionally display the description field from LibGuides (research guides) and LibGuidesAZ (databases).

Future:

• Consider doing the same to the recommendation modules for these data sources. Although I lean against it.

The test failure is occurring because the fixture doesn't match what an actual LibGuides response looks like. I'm guessing it was made with version 1 of the search widgets "API" instead of v2. I will need to create a new fixture (and will look for the instructions on that again -- it's binary so a pain.)

Details: The fixture is returning just a series of <a> links separated by <br>s. The current widgets return <li>s around each item.

Thanks, @maccabeelevine -- a few comments. Let me know if I can of more help with the test fixture issue.

Thanks for the improvements -- see below for one more thought. Other than that, let me know when it's ready to test and I can kick the tires more closely. :-)

@demiankatz ready to test now, thanks.

For future reference, this is the query used to generate the new fixture. The old one was clearly Bryn Mawr so I repeated that, but the response format has changed thoroughly. The data of course changed as well so tests are updated. IMHO saving the uncompressed version of the response is easier to understand when fixing tests.

Thanks, @maccabeelevine! I spotted one last tiny issue which I just took care of myself to expedite things (the type annotations in one file said "boolean" instead of the expected "bool"). I believe it's ready to merge now, as soon as CI passes.
