minor updates to godot-env

[GianiStatie]

Added some fixes for issues I encountered:

• using 0.0.0.0 instead of localhost in case you want to run the code from a Docker container
• appending the path instead of splitting by spaces so code won't break when paths have spaces in them
  • i.e. "environment/Dragon Jump/application"

Approved, there's still some discussion on Discord on details.
