feat(gatsby-source-wordpress): Fix false positive error if the URL an…

…d the responsePath are the same (#31612)

It is possible to get this output from the response:
{
  responsePath: 'https://<xxx>/graphql',
  path: '/graphql',
  url: 'https://<xxx>/graphql'
}
instead of
{
  responsePath: '/graphql',
  path: '/graphql',
  url: 'https://<xxx>/graphql'
}

It doesn't make sense to reject the request with GraphQL request was redirected
as the responsePath _is_ the url.
