From a protocol standpoint this PR is pedantically correct, we shouldn't have accepted other values. Not that anyone is ever going to send them. I've also added to this PR a length constraint on the values accepted for good measure. |

gh-103204: Enforce that HTTP version numbers must consist only of digits
Currently,
http.serveraccepts requests with version numbers preceded with'+'or'-', as well as those with'_'between digits. I am not aware of any other HTTP server that accepts such requests. This PR makes it reject those requests.Fixes #103204.
