Convert SVG to PNG bash script

[omenking]

I think the easiest way to convert the svg to png will be to take a look at this script and adopt it for this kit.

I took a look at the previous script and used the same library but wrote a new script.
The script is designed to run in Gitpod and takes in a simple pixel argument.
