* website: migrate to new nav-data format
* website: clean up unused intro content
* website: remove deprecated sidebar_title from frontmatter
* website: add react-content to fix global style import issue
* Add docs for MIME sniffing on metrics endpoint.
This was added in 1.7.2 last year but I realised we don't document it so it's kinda surprising Prometheus "just works" now.
* Update website/content/api-docs/agent/index.mdx
