Worked on improving documentation quality for the grafana/opentelemetry-rust repository, focusing on aligning code examples and documentation tests with the default usage of the OpenTelemetry Rust SDK. Refactored documentation tests by removing non-default feature initialization and updated metric templates to use the .build() method instead of .init(). Also removed a resource attribute from example snippets to better reflect standard SDK behavior. These changes, implemented using Rust and Jinja, aimed to reduce user confusion and streamline onboarding for new users. The work addressed a documentation bug, enhancing clarity without impacting runtime behavior or introducing new features during the period.
