Support OpenTelemetry 0.24

[NOBLES5E]

The upcoming release of OpenTelemetry 0.24 (https://github.com/open-telemetry/opentelemetry-rust/pull/1932) introduces breaking changes that affect the current implementation of tracing-opentelemetry.

Please update tracing-opentelemetry to support OpenTelemetry 0.24. This will ensure continued compatibility and allow users to benefit from the latest OpenTelemetry features and improvements.

Of course we will. Are you able to submit a PR?

I've encountered a challenge: OpenTelemetry 0.24 has made Tracer::provider() private, which impacts the current implementation. Given my limited familiarity with the tracing-opentelemetry codebase, I'm not confident in proposing a workaround for this change.

I wrote up some feedback for upstream here:

Today opentelemetry 0.24 was released. However the sampler is still private which seems to break this line: https://github.com/tokio-rs/tracing-opentelemetry/blob/7f4409a935608bb89e970956217a91945f285b0f/src/tracer.rs#L82

Thanks for letting me know. See https://github.com/tokio-rs/tracing-opentelemetry/pull/155 and https://github.com/open-telemetry/opentelemetry-rust/pull/1937.
