Features Added

• Added support for service version 2026-06-06.
• Added support for connection strings and account_urls to accept URLs with -ipv6 and -dualstack suffixes
  for BlobServiceClient, ContainerClient, and BlobClient.
• Added support for create permission in BlobSasPermissions for stage_block,
  stage_block_from_url, and commit_block_list.
• Added support for a new Smart access tier to StandardBlobTier used in BlobClient.set_standard_blob_tier,
  which is optimized to automatically determine the most cost-effective access with no performance impact.
  When set, BlobProperties.smart_access_tier will reveal the service's current access
  tier choice between Hot, Cool, and Archive.
• Added support for is_directory keyword in generate_blob_sas that generates directory-level SAS for blobs.

Other Changes
