Open in Colab badge

[JadeMaveric]

Is your feature request related to a problem? Please describe.
I've noticed several notebooks on github have an "Open in Colab" badge that let's viewers quickly setup and experiment with the code. I think this would be a super useful feature.

Describe the solution you'd like

1. Use the ColabBadge Action (repo maintainer will need to add this), and submit a PR that manually adds the {{badge}} to every existing notebook. This means that all new PRs will need to have a {{badge}} markdown cell.
2. Create a new GitHub action that automatically adds a markdown cell with the badge to the top of a new notebook.

Hey, could you please assign this issue to me and could you also add a level tag to it

[JadeMaveric]

I'm guessing the maintainers are busy, I've been waiting forever to be assigned to this.
