No worries, OP has a different thread and is aware of the “Go Module vs. GOPATH” development and how to approach them.
As far as all the documentations, we still need to set GOPATH. Even the installation guide is still requiring new setup to set GOPATH (Download and install - The Go Programming Language).

GOPATH and Modules
When using modules, GOPATH is no longer used for resolving imports. However, it is still used to store downloaded source code (in GOPATH/pkg/mod) and compiled commands (in GOPATH/bin).
