feat: add opentelemetry-wasi

[asteurer]

opentelemetry-wasi is a project to implement wasi-otel in languages with both WebAssembly and OpenTelemetry support. It currently resides at https://github.com/calebschoepp/opentelemetry-wasi/. We aim to make this set of WebAssembly guest language SDKs work seamlessly with the existing OpenTelemetry SDKs.

hey @asteurer, we discussed this proposal in the TSC (a while ago—the delay since is entirely on me, and I apologize!) and gladly accept your generous contribution!

To get this finalized, please ensure that the repository itself satisfies the requirements and update the proposal doc in this PR accordingly. Please also add the project itself to the projects README as part of this PR. If you re-request a review once that's done, we'll review and merge the PR, after which you can transfer the repository over to the BA.

Thanks Till! The repo satisfies the requirements laid out in the Requirements for Hosted Projects in the TSC charter. Also, I've created a pull request to have opentelemetry-wasi added to the list of projects: #153

Hey Andrew, could you update this PR to use the hosted project proposal template instead? I should've asked you for that in my last comment, and apologize for not doing so.

That template asks a few more relevant questions, and contains more things we need projects to do before we can move them over, such as adding a CoC. In doing that, can you also fold #153 into this PR?

(I tried finding out why we have a bunch of project proposals following the patterns you used here, and IIUC it's down to following the precedent set in #36, which predates the introduction of the proposal templates. We'll make sure to do a better job of guiding people through the process in the right way going forward.)
