test(template-require-form-method): exercise default-enabled path with no options

  With the rule default-enabled, `options: [true]` is redundant with no
  options. Switch most valid cases to bare strings so the tests
  exercise the default user path. Keep one `options: [true]` and one
  `options: [false]` as sentinels documenting that the explicit boolean
  forms still work.
