Fix bug in `Network::HTTP#initialize` with `ssl: {min_version: 1.1}` and `ssl: {max_version: 1.1}`

[postmodern]

It does not look like Float values for min_version and max_version are properly mapped in Network::HTTP#initialize_ssl.

Support::Network::HTTP.get('https://github.com/', ssl: {min_version: 1.1})

/usr/share/ruby/openssl/ssl.rb:179:in `set_minmax_proto_version': no implicit conversion of Float into String (TypeError)

        set_minmax_proto_version(version, @max_proto_version ||= nil)
                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
