Improved GitHub Pages support

[codesue]

It seems GitHub Pages fully supports this template now if you build and deploy the site using an Action instead of deploying from a branch. Here's the blog post explaining how to set this up. I was able to build and deploy my site using GitHub's default Jekyll workflow.

Exciting news! Thank you for reporting this, I appreciate it. I added a note in the README linking to this discussion.

Thanks for sharing this info @codesue 🙌! I have just enabled the GitHub action to deploy my site with GitHub Pages and the custom plugin for bi-directional links works perfectly!

For anyone else wondering how to do this: Go to Settings --> Code and automation --> Pages --> Source --> GitHub Actions, then the Jekyll workflow was selected by default.

Thanks @codesue @maximevaillancourt and @irenebosque for your inputs here.
I just opened #176 and the PR #177 to make it even easier.
All the best,
