docs: public/base_version comparison

[henryiii]

The current examples here are a bit misleading. They don't really show off the difference in .public vs. .base_version, or what they do. By adding the epoch to the public example and moving the .dev1 to the correct place, it makes the comparison as well as what they do clearer. I've also removed the . in front of .dev1 to show that both of them do normalize.
