chore(cloudformation-include): remove hardcoded S3 bucket names from integ test templates

[aemada-aws]

Issue # (if applicable)

Reason for this change

Three cloudformation-include integration tests fail with S3 bucket name collision errors (AlreadyExists, HTTP 409) because their CloudFormation template files contain hardcoded S3 bucket names. Since S3 bucket names are globally unique, these tests cannot deploy reliably.

Failing tests:

• integ.resource-tags-wtih-intrinsics — hardcoded BucketName: "cdk-integ-cfn-include-bucket2" in tags-with-intrinsics.json
• integ.novalue-nonstring — hardcoded BucketName: "test-novalue-boolean-bucket" in novalue-boolean.json
• integ.nested-stacks — hardcoded bucket name bucket-name-prefix-some-magic-bucket-name via Fn::Join in grandchild-import-stack.json

Original errors:

Resource handler returned message: "The requested bucket name is not available. The bucket namespace is shared by all users of the system. Please select a different name and try again. (Service: S3, Status Code: 409, HandlerErrorCode: AlreadyExists)

Description of changes

Removed hardcoded BucketName properties from the CloudFormation template JSON files used by these integration tests, allowing CloudFormation to auto-generate unique bucket names.

• tags-with-intrinsics.json: Removed BucketName property. The test's purpose is to verify CfnInclude handles tags with intrinsic functions (Fn::If, Fn::Select, AWS::NoValue) — the bucket name is irrelevant to this.

• novalue-boolean.json: Removed BucketName property. The test's purpose is to verify CfnInclude handles AWS::NoValue in place of a boolean (ObjectLockEnabled) — the bucket name is irrelevant to this.

• grandchild-import-stack.json: Replaced BucketName (which used Fn::Join with Ref: MyBucketParameter) with a Tags property using the same Fn::Join + Ref pattern. This preserves the test's intent of verifying nested stack parameter passing through CfnInclude while avoiding the name collision.

No .ts integ test files were modified — only the JSON template files they reference.

Destructive changes: All three tests have WILL_REPLACE on their S3 bucket resources. This is expected and intentional — removing hardcoded bucket names requires bucket replacement.
