Downgrade to vite v5 (+ dependency bumps)

[mkrause]

Bump dependency versions. Also, replace the use of --force in npm install/ci commands by package.json overrides.

This PR:

• Bumps a few dependencies
• Moves from sass to sass-embedded (https://www.npmjs.com/package/sass-embedded)
• Downgrades vite to v5, due to a blocking issue in vite-css-modules. This causes a runtime crash in dev mode (in particular, Storybook).
• Replaces the use of --force in npm install/ci commands by package.json overrides.
