fix: pin tailwind to version used in production

I've been trying to get the file list in the my development version working,
and was struggling even after pointing the website at the production version.

It turns out that when this website was updated from Tachyons to Tailwind, a stray `collapse` style was left on the file list table:

1a29aa9#diff-f8b81b815feea0a351b1a42218602943bda2f0d4cd44b009dbbbb5f7c8c35ddaR462

At the time this was fine! Tailwind didn't have a `collapse` style until version 3.2 and 3.0/3.1 were current at the time of the transition. The production site uses Tailwind 3.1 and works just fine.

However! The version specification for the `tailwind` package in the `website` project's package.json uses a "compatible with version" specifier (https://stackoverflow.com/a/22345808) which will bring in new minor versions as they're released, so my development version used Tailwind 3.4 which _does_ have a `collapse` style that is unfortunately _very different from the Tachyon style_ - rather than mapping to the `border-collapse: collapse` style as Tachyon does, `collapse` in Tailwind translates to `visibility: collapse` - a CSS attribute intended to let developers hide specific table rows. When applied to a whole table it results in the entire table being hidden. This was the source of the bug.

This PR:

1) moves to the `border-collapse` Tailwind style to match the original intent
2) pins Tailwind to the version specified in `yarn.lock` and any patch releases (which should not introduce or remove new styles)
