✨ feat: Add server Dockerfile (#2)

## Description

**What(what issue does this code solve/what feature does it add):**

We are adding the `Dockerfile` with all the scripts and programs to run
our games in.

**How(how does it solve it):**

1. Add `serverDockerfile` which contains all the docker code.
2. Add `.scripts` folder where we will store all the scripts; for
example in our case, where proton installation script will reside.

## Required Checklist:

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