Modernize JS build scripts (#19824)

- Remove __dirname, use file URLs instead
- Upgrade fabric dependency
- Use fs/promises syntax, this breaks node 12 but we require 14 already

The change in public/img/favicon.svg is not caused by the fabric
upgrade, but it seems it was not properly generated when introduced.
