Fix regression that dropped custom public/uploads path (render-exampl…

…es#18)

Strapi v4 lost the ability to override the public directory. v4.1.6
re-added that functionality but in a different way than how it worked in
Strapi pre v4. This PR[1] moves the configuration of the location of the
public directory to config/server.js. We want to override the default
only in production so that the public folder contents can be saved on a
persistent disk.

[1]: strapi/strapi#12534 Although this PR was
merged on Mar 25, the change wasn't included in a release until 4.1.6,
which was released on Mar 30.
