[Proposal] Remove current homepage and update docs landing page

[L1ghtmann]

A number of users have expressed that navigating to the docs from the current homepage is unclear and/or that the current homepage's existence doesn't make sense. To remedy this, I think it would make sense to remove the current homepage, update the docs landing page, and use that for the homepage. The current site only provides the docs and has a footer that provides the links on the current homepage, so I don't think we'd be losing anything in going through with this change.

Opening this as I am unsure how to best approach this and know others may have thoughts/implementation ideas.
