fix: shorten connection timeout to pypi.org for deprecation check for weaviate client (#21131)

+        # Fix to minimize the performance impact of the deprecation check in weaviate-client 3.24.0,
+        # by changing the connection timeout to pypi.org from 1 second to 0.001 seconds.
+        # TODO: This can be removed once weaviate-client is updated to 3.26.7 or higher,
+        #       which does not contain the deprecation check.
