What did you do?

The go version outputs wrong version,

jiazha-mac:openshift-tests-private jiazha$ go version
go version go1.22.0 darwin/arm64
jiazha-mac:openshift-tests-private jiazha$ which go 
/Users/jiazha/golang/go1.21/bin/go
```the 

### What did you see happen?

I checked the ENV, the `GOROOT=/Users/jiazha/golang/go1.21`, however, the `GOROOT='/Users/jiazha/go/pkg/mod/golang.org/toolchain@v0.0.1-go1.22.0.darwin-arm64'` in the `go env`, as follows,
```console
jiazha-mac:openshift-tests-private jiazha$ export GOROOT=/Users/jiazha/golang/go1.21
jiazha-mac:openshift-tests-private jiazha$ env |grep GOROOT
GOROOT=/Users/jiazha/golang/go1.21

jiazha-mac:openshift-tests-private jiazha$ go env|grep GOROOT
GOROOT='/Users/jiazha/go/pkg/mod/golang.org/toolchain@v0.0.1-go1.22.0.darwin-arm64'

What did you expect to see?

I can overwrite the GOROOT of go env.

I can get the right outputs after changing the GOTOOLCHAIN='auto' to GOTOOLCHAIN='go1.21.9', as follows, however, it's really confusing why the env cannot overwrite the go env.

jiazha-mac:openshift-tests-private jiazha$ export GOTOOLCHAIN='go1.21.9'
jiazha-mac:openshift-tests-private jiazha$ 
jiazha-mac:openshift-tests-private jiazha$ go version
go version go1.21.9 darwin/arm64
jiazha-mac:openshift-tests-private jiazha$ which go

This is expected for automatic toolchain upgrades from go.mod

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

It is the design. And it is really confused.

The 1.21 go command will search newer enough toolchain versions and call their "go" command instead.
The confusion comes from the fact that the whole process is implicit.

If you want to choose a Go toolchain version explicitly, you can try GoTV.
