Remove mermaid.js from footer and theme.

It is not used anywhere, and maybe should only be loaded if we actually do any mermaid diagrams.

This cuts down front page no-cache load from 1.71 MB to 914.43 kB.

Testing Done:
Loaded the front page. Also, searched for use of the mermaid shortcode, which was non-existent.
