fix: Use path+version dependencies for publishing to crates.io

Replace workspace dependencies with path+version format in opentelemetry-proto
and opentelemetry-otlp Cargo.toml files. This allows cargo publish to work by:
- Maintaining local path dependencies for development
- Providing explicit version numbers required by crates.io
- Ensuring publish dry-run succeeds for opentelemetry-proto

Note: opentelemetry-otlp publishing depends on opentelemetry-proto v0.30.1
being published first, following the dependency order.
