docs(s3): updated docstring for BucketPolicy()

[khushail]

Issue #31358

Closes #31358 .

Reason for this change

Exsiting CDK Doc on BucketPolicy mentions as Prefer to use which is misleading as it does not clearly states the reprecussions.

Description of changes

I have added a sample of what would happen if this is used along with other Bucket properties.

Description of how you validated changes

This is a minor documentation change
