Docs: No "latest" path in our doc

[ijemmy]

Description of the improvement

Summary of the proposal
When entering the root of documentation (http://awslabs.github.io/aws-lambda-powertools-typescript), it should be redirected to the alias "latest", just like in the Python version doc.

However, the current version redirects twice:

1. First to /latest
2. Immediately redirect from /latest to the actual version /0.2.0-beta.10.

We should make this behavior the same as the one in Python doc.
