Subject: [PATCH] Update Dockerfile to go1.18 syntax

As of 1.18, `go get <package>` no longer builds executables. `go install` should be used to install an executable instead.
See the deprecation message for more information: https://go.dev/doc/go-get-install-deprecation

Pinning to a specific go Docker image will help keep things from breaking unexpectedly in the future
