Subject: [PATCH] Do not export GOROOT

This has not been necessary since [Go 1.9](https://go.dev/doc/go1.9#goroot) at
least (although clunky to do so then) but definitely not since
[Go 1.10](https://go.dev/doc/go1.10#goroot).

This is cargo culting code that is more than 2 years out of date and runs into
issues when multiple go versions are used in an action run.
