gubernator/README: 'name' and 'value' are attributes, not child elements

These docs landed in 2f04de098e (Add properties info to junit xml,
2018-08-28, #9182), but since we began vendoring the backing XML types
in ce50d4c65c (calculate code coverage and produce junit xml,
2018-10-30, #9887) they've been:

  type Property struct {
    Name  string `xml:"name,attr"`
    Value string `xml:"value,attr"`
  }

The 'attr' label gets these stored as attibutes instead of as child
elements.
