go - WIT tuple type generated code uses unkeyed fields

[asteurer]

When the go vet -unsafeptr=false ./... command is run against the generated bindings, we get the following warning:

go.bytecodealliance.org/pkg/wit/types.Tuple2[string, string] struct literal uses unkeyed fields

This can be solved by changing a generated tuple from this:

result = append(result, witTypes.Tuple2[string, string]{value1, value2})

To this:

result = append(result, witTypes.Tuple2[string, string]{F0: value1, F1: value2})

@alexcrichton Will you assign this to me, please?
