Image build error - go version

[NorskNoobing]

I get an error when building the docker image using the provided instructions

git clone https://github.com/jayden-chan/puggies.git
cd puggies
./docker-build.sh

https://github.com/jayden-chan/puggies/blob/master/docs/Installation.md#building-docker-container-from-source

It seems like it could be as easy as to just install Go 1.20+ in the dockerfile.
