Fix footer icons being covered by report a bug button (#645)

Fixes #595

Add padding to the footer to prevent the "report a bug" button from
covering the footer icons.

* Modify `apps/web/src/components/layouts/site-footer.tsx`
- Add `pb-20` class to the `footer` element to provide additional
padding at the bottom.
