Make go env vars static

[liggitt]

Try to make the security linter happier:

Error: internal/goenv/goenv.go:10:14: G204: Subprocess launched with a potential tainted input or cmd arguments (gosec)
	out, err := exec.Command("go", append([]string{"env"}, varNames...)...).CombinedOutput()
	            ^

SGTM

would like to see the pull_request CI go green on this before merge... the lint failing on the previous PR didn't make it to running tests 😬

[cristaloleg]

Yeah, I'm waiting for CI ;)

[ldez]

The CI doesn't use go1.21 use it will be green 😄

well, at least we'd have more confidence it hadn't regressed something ;)

I agree, it was just a joke because my PR that add go1.21 is still red 😢 https://github.com/ldez/go-ruleguard/actions/workflows/go.yml
