Suggested doc: add recommendation for analytics page

This idea came out of a conversation with @nate-double-u around analytics for project sites. Analytics provide valuable information around content usage and can help a community prioritize pages to focus energy on across many levels of docs work, including release docs, localization work, etc.

Some possible recommendations ideas
* how to get analytics information. All CNCF project teams should have access to site analytics though [Netlify Analytics](https://docs.netlify.com/monitor-sites/analytics/). This feature must be enabled on each site
* make analytic information available to your community. Create a analytics page on your site, for example see the [Kubernetes Viewing Analytics page](https://kubernetes.io/docs/contribute/analytics/). Or present information regularly at community meetings
