Set up GitHub Pages and update the About section

[arnaucasau]

Instructions

The project now has the documentation deployed in a branch called gh-pages, but we need to set up the repo to use GitHub Pages by following the next 5 steps. Once the GitHub Pages is set up please update the repo's About section to display the new link.

1. Navigate to your site's repository
2. Click Settings
3. Go to Pages
4. Select Deploy from a branch, under the Source section on Build and deployment
5. Select the gh-pages branch and the / (root) folder in the Branch section on Build and deployment

The default URL where you can find your site is https://qiskit-community.github.io/qiskit-metal

For further information, you can see the GitHub Pages Quickstart and Qiskit/ecosystem#578.

Thank you! Ok, so i just did this, what's next

[zlatko-minev]

We will want to merge this branch in the main sometime?

Thank you @zlatko-minev! The page is now working at https://qiskit-community.github.io/qiskit-metal 🎉

No need to merge the branch, the gh-pages branch contains the docs built, and thanks to the new workflow it will be updated at each push to the main, similar to how we deployed to qiskit.org before :)

The only thing left in the issue is to change the link in the About section of the repo to show the new one.

P.S. If someday you want to deploy the docs from a stable version, the deployment changes introduced in this commit will need to be backported
