chore(deps): bump purecss from 3.0.0 to 3.1.0 in /site

[dependabot]

Bumps purecss from 3.0.0 to 3.1.0.

Release notes

Sourced from purecss's releases.

v3.1.0

The CSS is unchanged from 3.0.0, apart from comments and the LICENSE link in the banner.

• Replaced the deprecated Grunt build with ESM npm scripts (npm run build, npm test, npm run watch, npm run release). Build output is unchanged.
• Development now requires Node.js 26+ and npm 12+ (see .nvmrc).
• Removed the deprecated Rework (rework, rework-pure-grids, rework-mutate-selectors) from the build. Grids and base-context.css are now generated without it. Build output is unchanged.
• Added generateGrids() to the purecss package (require('purecss').generateGrids) for building custom grids. It takes the same arguments as rework-pure-grids' units() and returns the CSS string, with no Rework needed.
• The license banner now links to blob/main/LICENSE.
• Releases are now published to npm from GitHub Actions with trusted publishing, and include npm provenance.
