(bedrock): Class Agent / Interface: AgentProps doesn't detect changes on parameter "instruction", preventing CDK Deploy from updating.

Describe the bug

When modifying the Agent Prompt (parameter instruction for Interface AgentProps) in the Agent class, the CDK project doesn't detect any changes; e.g. cdk deploy stack >>> No changes detected. This means I have to edit manually the Agent's instruction or prompt, i.e. via CLI or Console, instead of running a simple CDK DEPLOY.

Example:

agent_instruction = """
You are a friendly virtual assistant for our department store...
... [truncated]
"""

# Create Agent. Hard-coded params: LLM Model. 
agent = bedrock.Agent(self, 'Agent01',
    name='virtual-assistant-agent',
    foundation_model=bedrock.BedrockFoundationModel.ANTHROPIC_CLAUDE_3_5_SONNET_V1_0,
    alias_name="virtual-assistant-agent-v1",
    instruction=agent_instruction,
    knowledge_bases=[kb],
    should_prepare_agent=True
)

So, if I modify the value of agent_instruction, CDK DEPLOY doesn't detect this.

Expected Behavior

CDK DEPLOY should detect and redeploy stack.

Current Behavior

CDK Deploy doesn't detect any changes. Resources (e.g. Bedrock agent) need manual intervention.

Reproduction Steps

Deploy the stack with X agent_instruction. Modify the agent_instruction Redeploy stack
