Change how webpack works

[ChasNelson1990]

          @mixmixmix - the cause of the `eval()` thing is indeed webpack (not next.js - we don't use that in this project) and is because of this line: https://github.com/fjelltopp/ckanext-who-romania/blob/e01ee9b07c245d883f58b57143df234a9595a05f/ckanext/who_romania/react/webpack.config.js#L10

I would document this and move on, I would like to move us all off of webpack soon and onto vite because webpack is a bit pants in many ways. If it genuinely a problem, change that line to 'production'.
