Description
If you want to get the statistics of an index with index.get_stats() like here, you get the corresponding data class (IndexStats), but you can't get any values from it with __getattr__, even though it is implemented in the class. Instead, you get the name of the attribute you wanted to access.

Expected behavior
A call to __getattr__ of the IndexStats class returns the value of the attribute (if it exists).

Current behavior
A call to __getattr__ of the IndexStats class returns the name of the attribute, not the value.

Example

import meilisearch as ms
ms_client = ms.Client(<host>, <master key>)
foo_index = ms_client.index("foo")

stats = foo_index.get_stats()
print(stats.numberOfDocuments)	# prints "numberOfDocuments" instead of the actual number of Documents

Environment (please complete the following information):

• meilisearch-python version: v0.34.1
