chore: disable all dependencies (we need a better approach)

🚀 chore(Cargo.toml): update dependencies and add optional tracing-opentelemetry feature
✨ feat(Cargo.toml): add opentelemetry and opentelemetry-jaeger dependencies as optional features
🚀 chore(Cargo.toml): update tracing and tracing-subscriber dependencies
The dependencies in the Cargo.toml file have been updated to their latest versions. The tracing-opentelemetry feature has been added as an optional feature to the dagger-core and dagger-sdk crates. The opentelemetry and opentelemetry-jaeger dependencies have been added as optional features to the dagger-sdk crate. This allows for the use of OpenTelemetry tracing in the application.

 A dagger sdk written in rust for rust.
 
+## Plan for next release
+
+- [x] Introduce [thiserror](https://docs.rs/thiserror/latest/thiserror/) for
+      better errors
+- [x] Add compatibility with `dagger run`
+- [ ] Add open telemetry tracing to the sdk
+- [ ] Remove `id().await?` from passing to other dagger graphs, this should make
+      the design much cleaner
+- [ ] Start MkBook on how to actually use the sdk
+- [x] Update to newest upstream release
+- [ ] Fix bugs
+  - [x] Run in conjunction with golang and other sdks
+  - [ ] Stabilize the initial `Arc<Query>` model into something more extensible
+

+# React Build
+
+This is based on the [Getting Started guide for Nodejs](https://docs.dagger.io/sdk/nodejs/783645/get-started#step-5-test-against-multiple-nodejs-versions)
+
+A simple react app is created with `create-react-app` which is built and tested by `build.js` or `build.ts`.
+
+Run:
+
+`npm install`
+
+and then:
+
+`node --loader ts-node/esm ./build.ts`
+
+or
+
+`node ./build.js`
