Purpose / why

Update the diagram at https://islandora.github.io/documentation/technical-documentation/diagram

The new version can be previewed at https://islandora.github.io/documentation/pr-preview/pr-2397/technical-documentation/diagram/

What changes were made?

• Since mkdocs-material has abandonded mkdocs, switched mkdocs to instead use zensical
• Broke up the architecture diagram into different mermaid.js diagrams
  • also added some custom CSS/JS to draw animations on the diagrams
  • also some custom JS to zoom into a mermaid diagram
• Fixed some other docs in the technical-documentation that were out of date
• Leveraged zensical's snippets extension. Wrote a bash script to parse our glossary.md into the format the snippets expect, loaded them with the proper config in mkdocs.yml so all our docs can reference terms in the glossary by wrapping the term in []

markdown_extensions:
  - zensical.extensions.preview:
      targets:
        include:
          - user-documentation/glossary.md
  - pymdownx.snippets:
