Bryan C. Mills 381252f312 cmd/go/internal/modload: use updateRequirements instead of editRequirements to add modules for missing packages
editRequirements does a lot of work in order to respect the upper
bounds of mustSelect, and as a result it doesn't provide many promises
about conserving other things (like root dependencies).

When we add modules for missing packages, we aren't dealing with upper
bounds at all, so we would rather avoid the upper-bound overhead and
preserve the root-dependency invariants instead.
(*loader).updateRequirements does exactly that; it just needs to be
told about the additional dependencies to add.

For #36460
