Patch BedrockRuntime Converse Stream Fix

[liustve]

Description of changes:

This PR applies temporary patches to address critical bugs in the AWS Bedrock runtime botocore instrumentation (version 0.54b0) that affect tool use functionality in non-streaming responses reported in: strands-agents/sdk-python#488

These changes are temporary patches and should be removed once we upgrade to opentelemetry-instrumentation-botocore version 0.56b0, which includes official fixes for these issues.

See:
open-telemetry/opentelemetry-python-contrib#3548
open-telemetry/opentelemetry-python-contrib#3544
