Describe the bug
I'm following the deployment guide for different servers (I want to deploy the admin panel - react app - to Netlify and the server to a droplet or similar). Still, the generated index.html file contains invalid paths to the generated js files.

Steps to reproduce the behavior
Create a Strapi example project using the quick start guide - https://docs.strapi.io/dev-docs/quick-start
Configure the server.js and admin.js files as described in the different server configuration guide - https://docs.strapi.io/dev-docs/admin-panel-customization#different-servers
Run NODE_ENV=production npm run build
The generated paths to the js files contain an extra slash, generating 404 errors:
src="//runtime~main.35ff75f1.js"
src="//main.19186bea.js"

Expected behavior
Create the index.html with the correct paths with only one slash to access the admin site using the http://yourfrontend.com/ URL. I think in this context the proxy recommendation not apply because this is a front-end app with the index.html file and js files, must work with any static hosting provider.
