Create a LOTE3 documentation landing page

We have plenty of high-quality documentation after LOTE3, with more in the pipeline. However, documentation wikis are buried in as nodes in the Making LOTE3 group, which has quite a lot of content in it. I suggest a landing page for documentation – it could be as simple as a page of links. We could also repurpose the program page to the same effect, with the titles of the session now linking to documentation wikis.
