Docs: fix cleanup command in cdk example

[niko-achilles]

What were you searching in the docs?

Example with cdk, sample application .
Location: https://github.com/awslabs/aws-lambda-powertools-typescript/tree/main/examples/cdk

Is this related to an existing documentation section?

https://github.com/awslabs/aws-lambda-powertools-typescript/blob/fa236b94b6532685588edd2f440c911dc6de56ab/examples/cdk/README.md?plain=1#L75

How can we improve?

The instruction on how to delete the sample application is described as follows:  
To delete the sample application that you created, run the command below while in the `examples/sam` directory:

cdk delete

Thoughts:
- The location to run the command is accidently wrong (`examples/sam`) 
- The command to delete is accidently wrong (`cdk delete`)

Got a suggestion in mind?

The proposed update is to correct where (location) to run the command for deleting sample cdk app and the command that should be used deleting (how).
E.g: in cdk the word destroy is used, cdk destroy, npx cdk --destroy

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.

Suggested edit:
