[cranelift] CONTRIBUTING.md is a dead link

[jyn514]

Probably got lost in the switch to wasmtime. cranelift/README.md links to cranelift/CONTRIBUTING.md, but there's no file there. Not sure whether you want this to link to CONTRIBUTING.md or something in cranelift/docs, so I didn't make a PR.

Linking to the wasmtime-level CONTRIBUTING.md would make sense to me.

Is there a reason not to add back the old CONTRIBUTING.md file? https://github.com/bytecodealliance/cranelift/blob/3d1cdec0837684b1656bcb6194be6c31302b5d3e/CONTRIBUTING.md

I suspect it was removed to remove duplication; @alexcrichton?

@jyn514, what does the cranelift file have that is missing in the wasmtime file? (I mean what information do you feel is important and missing?)

[jyn514]

Actually, looking back at both it seems like they cover most of the same info, so I'd be ok with only keeping the wasmtime website. I was a little put off by most of the sections on the website being missing, but 10. Contributing all seems to be there.

Oh oops sorry about the broken link! I removed the one in cranelift and merged it with the wasmtime contributing docs. The top-level CONTRIBUTING.md is just a thin shim pointing to those docs. I figured there wasn't much use in having two CONTRIBUTING.md files, but I think it's fine for the README to point directly to the online docs!
