http: remove the space requirement after status-code

It was introduced in 294136b75411893c5, but not shipped in a release. It
has caused problems and after checking, the browsers don't insist on it
even if RFC 9112 says it is mandatory.

Adjust test 2 to do a response without the space.

Closes #16728
