wait_for_task timeout

[sanders41]

@long2ice I saw in c9ab8a6 you extended the default timeout for wait_for_task. I had a request from a user to make it possible to wait indefinitely that I implemented. This is possible in meilisearch-python-async >= 1.2.0 by passing None to the timeout. The update you made is no problem, I just wanted to let you know the None option is now available if you want to use it.

Thanks! I will change that
