v0.36.0: feat: make ruby work again (#650)

- ruby now supports streaming and tracing
- ruby does _not_ yet support: custom trace decorators, images, or
dynamic types
- ruby compilation is not baked into the default `cargo build` - too
much stuff requires ruby-specific compiler flags
- `baml` gem 0.1.10 has been released and contains the latest stuff
- `release_language_client_ruby` now works
- ruby codegen has been updated, and needs to be shipped in the vscode
extension
- fix: codegen for the default `baml_client` used to automatically
happen in `baml_src`, it now happens in `baml_src/..`
- chore: delete integ-tests2
