cmd/go: fix GOTOOLCHAIN parsing for +auto

2023-07-12T18:25:28Z

The call from toolchain.Select to gover.FromToolchain was passing the wrong argument but this was masked by gover.IsValid being a little bit too lax. Fix and test IsValid, which then breaks the existing gotoolchain_local test, and then fix toolchain.Select to fix the test. Fixes #61068.
