Make QNetworkAccessManager to discard all informational (1xx) replies
from HTTP servers with the exception of 101.
According to RFC 9110:
"A client MUST be able to parse one or more 1xx responses received
prior to a final response, even if the client does not expect one.
A user agent MAY ignore unexpected 1xx responses."
Status code 101 is an exception because we use it to upgrade to http2
cleartext when it is enabled.
