Add opentelemetry-instrumentation-logging to the Python layer

[darylweir]

We've been using the Python OTel lambda layer to trace our lambda functions. We'd like to get the trace/span IDs automatically into the logs so we can connect traces to execution logs.

Since the lambda layer doesn't include opentelemetry-instrumentation-logging, we need to install that package into our lambda dependencies. However, that pulls in opentelemetry-instrumentation and opentelemetry-sdk as transitive deps, and those are in the layer. We end up with two copies of those packages in our lambda bundle, and this opens the potential for conflicts to arise if the instrumentation-logging version gets out of sync with the layer.

Ideally, opentelemetry-instrumentation-logging would be included in the layer directly.
