Support renaming files in directories in `az storage`

az storage file and az storage directory

Is your feature request related to a problem? Please describe.
The missing rename operation is very common and would make for a great feature that completes the rest of the commands.

Describe the solution you'd like
The az storage file and az storage directory utilities should include a rename operation.

Describe alternatives you've considered
The alternatives are to either:

• Using the REST API which provides Rename File and Rename Directory.
• Setting up Azure PowerShell which provides Rename-AzStorageFile and Rename-AzStorageDirectory.

Additional context
Renaming a directory through the REST API is much less convenient than any of the storage commands:

az rest --method put \
  --headers "{ \
    \"x-ms-version\": \"2024-11-04\", \
    \"x-ms-file-rename-source\": \"$SOURCE_DIR\", \
    \"x-ms-file-request-intent\": \"backup\" }" \
  --url "$TARGET_DIR"'?restype=directory&comp=rename' \
  --resource "$SHARE_URL"
