✨ feat: Add a separate image to build warp (#23)

## Description

**What(what issue does this code solve/what feature does it add):**
Build times for netris:server are way too long. so the idea is to move
warp into it's own container then build from there.
Later on first release we might drop this for a better solution.
**How(how does it solve it):**
1. Added the very own netris:warp

## Required Checklist:

- [x] I have added any necessary documentation and comments in my code
(where appropriate)
- [x] I have added tests to make sure my code runs in all contexts
