- Pulled common content from multiple pages into new partials
- Refactored install/index to be OS-based so I could add linux-distro-based instructions to install-consul-cni-plugins.mdx partial. The tab groups on the install/index page do match and change focus as expected.
- Moved CNI overview-type content to networking/index
- Refactored networking/cni to include install CNI plugins and configuration content (from install/index).
- Moved CNI plugins explanation in bridge mode configuration section into bullet points. They had been #### headings, which aren't rendered in the R page TOC. I tried to simplify and format the bullet point content to be easier to scan.
