Fix baseline grid toggle styling on standalone examples

[Nayab-Gauhar]

Import switch component styles in examples.scss to properly style the baseline grid toggle on standalone examples.

Fixes #5286

Done

• Added @include vf-p-switch; to scss/docs/example.scss to import switch component styles
• This ensures the baseline grid toggle is properly styled on all standalone examples

QA

• Open any standalone example page (e.g., https://vanillaframework.io/docs/examples/patterns/accordion/)
• Verify the baseline grid toggle button in the bottom toolbar is now properly styled
• Check that the switch component displays correctly with proper styling

Hey @Nayab-Gauhar , thanks for your interest!

This causes the build to fail; see CI logs.

I'd suggest checking out /guides/hacking.md and running the project locally, with dotrun to start the project and dotrun watch in another terminal so you can live-refresh SCSS changes. Please make sure the PR builds. Let me know if you have any questions :)
