Man page example 3 refers to dh1024.pem which does not exist

Man page example 3 refers to dh1024.pem which does not exist in openvpn-2.4.7/sample/sample-keys/. Better to replace it there with dh2048.pem:

   Example 3: A tunnel with full TLS-based security
...
       For Diffie Hellman parameters you can use the included
>>>    file dh1024.pem.  Note that all client, server, and certificate
       authority certificates and keys included in the OpenVPN distribution
       are totally insecure and should be used for testing only.

...

       On alice:

              openvpn --remote bob.example.com --dev tun1 --ifconfig 10.4.0.2
>>>           10.4.0.1 --tls-server --dh dh1024.pem --ca ca.crt --cert
              server.crt --key server.key --reneg-sec 60 --verb 5
...

@dazo: since you're on the manpage right now...
