Use the Pygments syntax-highlighting library to parse
and render the YAML rule content. This way we don't have
to manually traverse the rule nodes and emit lists; instead,
we rely on the fact that YAML is pretty easy for humans
to read and let them consume it directly, with some text 
formatting to help hint at the types/structure.

capa (the library) has routines for deserializing the YAML
content into structured objects, which means we can use tools
like mypy to find bugs. So, prefer to use those routines instead
of parsing YAML ourselves.

Run and fix the issues identified by the following linters:

  - isort
  - black
  - ruff
  - mypy

Add links to the following external resources:

  - GitHub rule source in capa-rules repo
  - VirusTotal search for matching samples

Update the rules landing page to accept a HTTP
query parameter named "q" that specifies an initial 
search term to to pass to pagefind. This enables
external pages link to rule searches.

Import header from root capa landing page.
