Fix Issue #8999 (#9014)

### Motivation

https://pulsar.apache.org/api/python/ points to the first ever released Python API. This was confusing me for the longest time until I figured out that the latest API doc is actually at https://pulsar.apache.org/api/python/2.7.0-SNAPSHOT/

https://pulsar.apache.org/api/python/ should redirect to the latest version and the page itself should clearly state which version it documents.
