Updated buildkit, starter site, demo objects, workbench, and solr config

Updates everything in the build to current releases.

Tested locally. Ran into an issue where the collection page did not show children:

Two children exist.

Looks like a Solr configuration issue:

Also noticed rights field is being rendered as plain text rather than HTML.

Everything else I checked seemed to work well.

@nigelgbanks Weird - it looks like you still have the old Solr config and the old template file for the workbench config file.
Did you re-run the build command?

[nigelgbanks]

I did rerun the build command, it seems like there was some caching issue though. I wiped my docker build cache and then it worked as intended!

Thanks @nigelgbanks !
