Feature: Development Only Scripts template

[Rasmizzle]

Feature:

• Added Networkteam.Neos.Vite:Helper.DevelopmentOnlyScripts for including scripts in development context only.
• Added Networkteam.Neos.Vite:Helper.IsDevelopmentOnly as a boolean check if inside development context.
• Added Networkteam.Neos.Vite:Head.Assets for head-scripts, including react-refresh-runtime, which is needed for any react-base development.
  • this is a philosophical question whether we want to auto include it here...? I'd say there is nothing wrong with it, as most of the time users of this package use react; it is only included in dev-context.
• Added Networkteam.Neos.Vite:Body.Assets for wrapping projects body scripts.

I'd like some feedback whether this is a valid approach or if one rather wants to leave more configuration to the customer project.
