GOTOOLCHAIN=local is needed to pin the Go version

Should we make this <lowest-version-supported>, oldstable, stable ? That also reduces the need to update versions (we'll continue testing some "lowest" version", and the other two test currently supported versions.

See opencontainers/image-spec#1229 for an example.

Let me just remove the last commit so we can merge this.

Some spelling issues to fix;

./config-vm.md:78: conains ==> contains
./config-vm.md:78: minimun ==> minimum
./specs-go/config.go:691: containes ==> contains, container, contained
Error: Process completed with exit code 65.

Those are (relatively) new, from #1209. It's a pity that it was merged earlier than this PR.

Fixed now.
