Documentation mentions non-existent TLS version

[viccie30]

The documentation mentions that HTTP/2 requires at least TLSv2:

hypercorn/docs/discussion/http2.rst

Line 15 in 6cb9c5c

and TLSv2 the minimal TLS version servers should support. By default

That version doesn't exist (yet) and the standard mentions TLS 1.2 as the minimum requirement.
