scripts/installers/install-go.sh is broken with no version

[idlewis]

go 1.20 had binary downloads number: 1.20 1.20.1 1.20.2 etc... go 1.21 instead has: 1.21.0 1.21.1 1.21.2

This breaks install-go.sh if it is run with no arguments, as it currently tries to install go 1.21 , which doesn't exist.

This also means that running make docker-build currently doesn't work A work around is to run the docker build directly, and specify the go version to use.
