Improve infrastructure diagrams

[jaimergp]

#34 added some preliminary diagrams but these are not final. Diagrams are great to create a visual image of what's out there, which seems handy in conda-forge, given the amount of moving pieces we have.

I started a mindmap diagram with mermaid to provide this mental model of all the infrastructure (without relationships, just the inventory). You can see it here:

• https://cf-infra-docs.netlify.app/docs/reference/infrastructure/diagrams/ - this doesn't work right now (see Can't render mindmap mermaid diagrams facebook/docusaurus#9032)
• See the mermaid.live representation instead for now

Once we have that I guess we can start breaking it down in chunks, with each chunk having the relationships between elements when needed.

Some work had been done in https://cf-infra-docs.netlify.app/docs/advanced/automation/
Still need to build on and improve the content and structure

Take advantage of the momentum reviewing cf-infra-docs to see if there are opportunities to complement the docs with figures that make everything a bit easier to understand. No need for them to be self-explanatory.
