add links to consuming projects in readme

[guybedford]

This updates the readme to note projects which are using StarlingMonkey (expected to be a list that can grow over time), which also seems useful for users to easily find where to use StarlingMonkey without having to build it themselves.

Adding this makes a lot of sense, yes. I wonder though if we shouldn't introduce an ADOPTERS file like other projects have? E.g. Wasmtime has such a file, with a structure I quite like.

We could then include a link to that file as part of a single-sentence paragraph here.

Nice, one counter argument is that I did not know that page existed until you mentioned it. I really like the format though and table, but I think highlighting production users at the forefront of the readme can help build confidence in the project.

I agree, yes. That's what I was trying to address with the suggestion of including a mention/link in the README, but maybe inlining it is still the better call. In that case, maybe we do the inverse: introduce an ADOPTERS file that just contains a sentence with a link to this section of the README, so people expecting that kind of pattern immediately find what they're looking for?

Added a separate file and short summary, let me know your thoughts.

I like it!
