move AnVIL assets

[KatherineCox]

Closes #67

Moved AnVIL style assets into their own subdirectory within assets. Then if people put other things in assets they won't get clobbered by updates from AnVIL_Template.

Updated sync.yml to point to the subdirectory.

There are a couple of things left in the top level of assets right now since they came from OTTR and I'm not sure where they're being used, and don't want to break things by moving them

@cansavvy a couple of questions about the files in assets

Are these files ever being used? If so where? When I try "searching" the OTTR_Template repo, GitHub it doesn't find them, but I don't know how thorough that is.

1. style_coursera.css - no search results
2. toc_close.css - no search results
3. hideOutput.js - I see it in <script> tags that are commented out.

Wondering if these are leftovers from earlier iterations that are safe to get rid of (both in AnVIL_Template and in OTTR_Template)? Or if they are being used somewhere? I haven't done any coursera or leanpub rendering, so I'm unfamiliar with what's needed there.

Those files are all here: https://github.com/jhudsl/OTTR_Template/tree/main/assets

toc_close.css is only needed for Coursera or Leanpub rendering so you can get rid of it if you don't wish to use it.
hideOutput.js I don't know what this is, maybe @carriewright11 knows?
style_coursera.css - is an old version of a file and can be deleted, I'm going to delete it on OTTR_Template now.
