[BUG] Missing boto3 dependency when using AWS Bedrock provider

[Ray0907]

Description

When using AWS Bedrock as the LLM provider with CrewAI and LiteLLM, the service fails due to a missing boto3 dependency in the LiteLLM Bedrock handler path.

Steps to Reproduce

crewai run

Expected behavior

• boto3 should be included as a required dependency when using the AWS Bedrock provider
• The dependency should be properly handled within the LiteLLM Bedrock handler
