Read response from http2 or http3

[nothinux]

Go http.ParseHTTPVersion() could not parse http version without minor version, like HTTP/2 or HTTP/3.
So in this PR, I add a minor version if the response doesn't include minor version in HTTP response.

Thank you @nothinux for creating PR for this bug, initial test shows the following error after the change.

I think that issue because the Content-Length is wrong or broken, so its throw an unexpected EOF exception.

maybe you can test again with a different http response @ehsandeep

I have tested myself by getting a response from https://golang.org/doc/install, and test that response

$ curl -i https://golang.org/doc/install > golang-response.txt
$ echo golang-response.txt | ./nuclei -passive

I also add new test, for testing live response.

i don't have an idea to handle situation when Content-Length is broken, any suggestion?

Thank you
