text: Title: Resolve relative paths from the schema location
  Body: ## Problem
  
  <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] -->
  
  Currently, relative paths for partial type generators are resolved based on the current working directory, this can make it annoying as the client can only be generated from one specific directory.
  
  ## Suggested solution

  Resolve paths relative to the location of the prisma schema file.
