Documentation needs update

Hello!

In the current Python SDK(4.0) documentation the Cluster creation has a different version from GitHub(the Github one is the correct version).

• official documentation from docs.couchbase.com:
  cluster = Cluster('couchbases://{}'.format(endpoint), .....)

• official documentation from https://github.com/couchbase/couchbase-python-client:
  cluster = Cluster.connect('couchbase://{}'.format(endpoint), ......)

What:

• the cluster is created using the method `connect`
• the suffix of the connection string is couchbase:// not couchbases://

Hope this can help.
