#1761 Document Islandora Advanced Search

[manez]

Purpose / why

Create a new page documenting how to configure new Advanced Search. Resolves #1761

What changes were made?

New .md, new screenshots in the assets folder, and new entry in mkdocs.yml to add the page to the tree.

Verification

Review! This is mostly lifted from the great docs @nigelgbanks already made in the readme: https://github.com/nigelgbanks/islandora/blob/8.x-1.x-advanced-search/modules/islandora_advanced_search/README.md, with some changes to make it a docs page instead of a readme and to fit the style guide.

I tested locally. It can't find the images, I think you might need ../../assets?

Gave that a try! They are now all broken in my repo, but if they built in the real docs, then 👍

I think that's one .. too many, you need to go one level up and then one down into the assets folder:
../assets/

[manez]

That does look better in the browser view
