Stemmer is not defined in Python API search

[jrtitus]

I'm not sure if this issue should go here or in the plotly.py repo.

Steps to Reproduce

1. Go here: https://plotly.com/python-api-reference/search.html
2. Open (F12) DevTools
3. Search for something

Result

Uncaught ReferenceError: Stemmer is not defined
    at Object.query (searchtools.js:158)
    at Object.performSearch (searchtools.js:146)
    at Object.init (searchtools.js:79)
