Dependencies: upgrade `rollup/plugin-commonjs`

[humitos]

The latest working version is rollup/plugin-commonjs@26.0.3. However, the latest available version is 28.0.1

When upgrading it fails because of:

 🚧 Browser logs:
      SyntaxError: The requested module './../node_modules/ajv/dist/ajv.js' does not provide an export named 'default'

 ❌ Could not import your test module. Check the browser logs or open the browser in debug mode for more information.
