In frontend, add context aware links to Home Assistant help topics for built-in integrations

I was unable to find any links to Home Assistant help topics within the Home Assistant frontend outside of the Add-ons and Integrations pages. The magnifying glass icon at the top right of many pages turns out to be an Entity Filter rather than a general topic search filter, which is confusing (at least compared to other web interfaces where a magnifying glass is often a more general help or topic search).

It would be nice to be able to search for Home Assistant help topics (e.g. templates, input helpers, or anything else that requires explanation) from anywhere within the frontend interface. Right now, I have to open a new Google window to search for Home Assistant help topics.

I’m using Home Assistant OS 8.1 with Core version 2022.5.5, Supervisor 2022.05.3 and Frontend version 20220504.1.
