Make preview a per site configuration #867
Description
Package
next (Drupal module)
Describe the feature request
When operating multiple next.js sites from one Drupal, I may have different preview approaches depending on the type of site I have. As such I'd like to set the preview plugin on each site. However right now, its a global module-level configuration.
Describe the solution you'd like
Provide configuration per site to define the preview plugin at a site-level.
Describe alternatives you've considered
I guess you can technically get around this constraint with a custom module to alter the current implementation but its not ideal.
Additional context
Instead of an iframe previewer, I wanted to redirect the user to the next.js site. So I also wanted a redirect previewer plugin also.
