Subject: [Acme] stray Accept: application/pkix headers

Hi,

I've noticed that there are two stray "Accept: application/pkix"
headers in examples where they don't make sense (as the answer is
application/json):

 - Section 7.5 (Identifier Authorization), top of page 50
 - Section 7.5.1 (Responding to Challenges), top of page 53

I think they have been accidentally copied there; they were inserted in
the first commit of https://github.com/ietf-wg-acme/acme/pull/445

Best regards,
Felix
