Proposed change

Icons are a large part of Home Assistant, however we have little information in our official documentation about them. In this PR I have added a dedicated page to frontend icons that provides our users with information on how to find icons, suggest new icons and aliases, and even contribute icons to the MDI project!

Additionally, I have updated the Frontend landing page.

This is only a first stage. I would like to expand on the icon documentation by adding another page with a curated list of icons by entity category in the future. However, that will require getting MDI into the docs site (replacing Font Awesome), which I have started to do in another branch.
