This PR is adding the support for the new Github issue beta page.

🐛 Recommendations for testing

All changes should be tested across Chrome and Firefox.

First commit is formatting applied.

1. Use this branch and link it to the extension.
2. Go to Github, on the issue page (if you have the beta view enabled) you should now see the button.
3. Ensure that the title and the issue number are present in the TE description.
4. Also, it should automatically connect the first project (if exists).

We are rendering the button twice, e.g. here.

Replicated the issue, it was double rendering as we have the Project Page Side case that was activating with this new one.

Now it should work fine @izontm.
