Actively invite people to contribute

When asked about contributions I said:

Two biggest things are support and plugin research/development

Lots of people are asking questions in tickets - but the bigger thing is figuring out things like which models work best for different plugins, do they need extra configuration? And generally getting more models working
(I really wish llm-gpt4all didn't spew xtra junk to stderr)

Really I'd like there to be a solid chance that any model you might want to try can run in LLM, either via an existing plugin (with documented steps to run it) or via a new one

The most ambitious version of LLM is that it has a documented, clear path to getting model X running, on multiple platforms, for as many X as possible - and that it's widely used enough that model providers themselves start contributing plugins or plugin configuration documentation as part of their own releases

I need to actually turn this into a proper invitation - update the README and https://llm.datasette.io/en/stable/contributing.html page and really put the word out that I'm looking for help.

Start by reviewing the repository README and the contributing page at https://llm.datasette.io/en/stable/contributing.html, then compare their current guidance with the contribution needs described in this issue. Done means both pages contain a clear invitation covering support, plugin research and development, model compatibility, and documented setup paths; the requested outreach should also be clarified.
