Document: support iceberg on azure blob

Description

Support iceberg sink and iceberg source on azure blob.

Hi @wcy-fdu, @chenzl25, I just added doc about supporting iceberg source and sink on Azblob, and wanna double check if we support iceberg table engine on azblob? That is to say, if we support the syntax like the following

CREATE CONNECTION public.conn WITH (
   type = 'iceberg',
   catalog.type = 'rest',
   catalog.uri = 'http://localhost:8181/catalog',
   warehouse.path = 'azblob://demo',
   azblob.account_name = '<account>',
   azblob.account_key = '<key>',
   azblob.endpoint_url = 'https://<account>.blob.core.windows.net/',
   catalog.name = 'demo'
);

Currently, I didn't find azblob-related params here. Any comments are welcome!
