This removes the "[How It Works](https://www.home-assistant.io/lovelace/how-it-works/)" link from the Lovelace sidebar navigation. The actual page will still exist, this simply demotes it from the sidebar nav for now.
Reasoning is, the "How it Works" page is obsolete and will only cause confusion and frustration. New users click on "How it works" expecting to see a user guide for Lovelace, but instead they get some nerdy tech document comparing it to the older "States" UI which no longer even exists.
I would like to eventually rewrite the page to be more user-focused and then re-add it to sidebar.
* add dashboards
Based on this issue - https://github.com/home-assistant/home-assistant.io/issues/12462
As dashboards are not limited to YAML mode, it makes the information on them hard to find when it's a part of Lovelace YAML mode page.
I propose to add informatin about dashboards' configuration to the page about Views and rename it accordingly.
* move dashboards to views
* add link to dashboards
* dashes instead of underscores
* change link to Dashboards & Views
* add /lovelace/views
