Update Rollup dependencies

Manually update some Rollup dependencies, with configuration changes if required.

• Update rollup to latest.
• Update @rollup/plugin-node-resolve to latest.
• Update @rollup/plugin-replace to latest.
• Replace deprecated rollup-plugin-babel with @rollup/plugin-babel.
• Replace deprecated rollup-plugin-commonjs with @rollup/plugin-commonjs.
• Replace deprecated rollup-plugin-node-polyfills with @rollup/plugin-inject. It doesn't say so on the website, but when rebuilding yarn.lock, it says: warning rollup-plugin-node-polyfills > rollup-plugin-inject@3.0.2: This package has been deprecated and is no longer maintained. Please use @rollup/plugin-inject.

I didn't update rollup-plugin-vue. I think the latest version requires Vue 3. If I update it, it can't process the site. It might be easily fixed, but that could be separate.
