Readme Gallery Demos Broken

[Gamrix]

Description

All of the demo links gallery examples in the README.md in this repo are dead.

Steps/Code to Reproduce

1. If logged into Plotly, log out (I don't have an account, so I am already logged out).
2. Click a Demo link in one of the gallery items. (eg: https://dash.gallery/cytoscape-elements )

Expected Results

I expect it to link to a working demo example.

Actual Results

I get errors such as the following
