Update Jekyll and fix the theme

We want to be up to date.
So I updated Jekyll to the latest version. [1]

Lately, we have been favoring GitHub Actions
over the built-in GitHub Pages.
I also switched the theme from the remote version
to the version installed from the gem.

This forced us to make a few configuration changes.
We had to add a few gems that were previously
loaded via GitHub Pages.

Additionally, there were deprecation warnings related to Sass gem. [2]
This in turn made me have to add `jekyll-sass-converter` gem [3]
in a specific version.

After these changes, everything works.
However, there is definitely space for optimization.
