	* Print all entities and roles for a bucket's Default ACL.

@yash30201
So, the doc has a sample for C# to "view" the default ACL for the object.
While the other languages have a sample to "add" the default ACL.

Before merging please contact the Storage owners to understand why that is the case.

Suggested change

	function print_bucket_default_acl($bucketName)
	function print_bucket_default_acl(string $bucketName): void {

Use this as a reference. Same for the other 2 PRs.

Thanks for pointing this out. I previously did discover this and found that this sample is for adding more roles to the default ACL so that this modified ACL becomes the new default one. It serves a different purpose than just printing the default ACL and isn't related to this sample. Moreover, I think that the error on that C# sample is wrong region tag(as that sample seems to be just doing the work of this sample instead of that one). I also discovered some issues like this in PHP samples, plan to rectify them later.
