Samuel Ryan 6b66663d04 fixes 1xx code source reference numbering
For the sake of consistency and future proofing (there may be a
scenario in future where we need to access the source URL for each
status code programmatically) it makes sense to have them consistently
numbered. The source document will always be reference link ID 1.

:continue

The 100 (Continue) status code indicates that the initial part of a request has been received and has not yet been rejected by the server. The server intends to send a final response after the request has been fully received and acted upon.

When the request contains an Expect header field that includes a 100-continue expectation, the 100 response indicates that the server wishes to receive the request payload body, as described in RFC7231 Section 5.1.1. The client ought to continue sending the request and discard the 100 response.

If the request did not contain an Expect header field containing the 100-continue expectation, the client can simply discard this interim response.
