Copy 'Public' folder at 'mailing server build'

[tobdru]

We have translations and images as static files in our project and would like to get them in our build output. As a workaround we copy them after the buildstep from ./public to .mailing/public.

Would be great to have the standard nextjs option to have a public folder wich is then bundled in generated .next folder.

As an alternative it would be great to have a short note in the documentation about how to add resources.

Hint i think this could then be added in linkEmailsDirectory function.
