Update Documentation Link on Pypi Page #3653
Description
The Pypi package page for google-cloud-language v0.25.0 links to the wrong Documentation site (might just be out of step with head).
- Is: https://googlecloudplatform.github.io/google-cloud-python/stable/language-usage.html
- Should be: https://googlecloudplatform.github.io/google-cloud-python/stable/language/usage.html
I couldn't find where this is versioned, otherwise would have submitted a PR.
