Add Certbot to Ubuntu 20.04

The Certbot documentation makes it look like you can only install Certbot using snapd. That doesn’t appear to be true, at least for initial install. This works fine:

sudo apt install certbot
sudo apt install python3-certbot-apache

And then the usual steps after that:

sudo certbot --apache -d

I haven’t been through the cert renewal process yet on Ubuntu 20.04, but I don’t see why it wouldn’t work, since it essentially follows the same steps.
