footer updates

[drammock]

1. changes statistical -> scientific in the footer text
2. adds a new plugin to pull in the footer links and social icons/links from a JSON file
3. tweaks spacing/breakpoints/CSS

Current state:

TODO:

• I cannot get the :columns: property of grid-items to have any effect, so to shrink the space allocated to the logo I had to embed another sub-grid for the logo + description text
• Having trouble adjusting the spacing between footer links. Right now it seems to be governed by the gap-4 class on the outer grid, and adding e.g. gap-1 to the inner grid didn't override that
• add the social icons (and copyright notice?) to the rightmost cell
• other general tweaking of spacing; could resort to custom classes + CSS if necessary but was hoping to get something nice-looking using only the grid system and existing gap-*, my-* and mx-* classes

@stefanv (or anyone else!) feel free to push commits here to get it over the line

I did another review, flagged a few minor issues with suggested fixes.
These are mostly minor under-the-hood changes that site visitors would never notice.

Everything looks and feels good when I run it locally check it by hand, social links work properly.
There are a few gaps in the footer-links on the Test Site, which I assume is fine; SPECs, Press kit, etc. are not found, but target the appropriate site url.

thanks @lundybernard. I'll take a look tomorrow. FYI your PR is against drammock/main instead of drammock/footer but it's fine, i can easily merge/cherry-pick the commits locally and push them where they need to go.

OK I've incorporated all of @lundybernard's changes. Should be ready to go. Demo of breakpoints:
