Addressing #1395 but with a different solution from #1478, using
semantic versioning based on implementation found
[here](https://distresssignal.org/busting-css-cache-with-jekyll-md5-hash).
Implemented a way of calculating the hash for both a single file or
directory. This way we can calculate the hash for when there is a change
in the `_sass` dir, for example, or in the contents of a single file.
Examples of generated outputs of the plugin:
```

Also added links to news and publications from respective section

it consistent with the previous look.
This PR replaces the jekyll-responsive-images with jekyll-imagemagick for responsive WebP images.
WebP images are much smaller compared to PNG and JPEG, faster to load and most of the modern browsers recommend it.
