Issue:
[feature] Add support for Pop!_OS to package_manager
### What is your suggestion?

[Pop!_OS](https://pop.system76.com/) is an Ubuntu-based Linux distribution. It would be great if it could be added to the list of distributions that support `apt-get`. Its `distro.id()` is `pop`.

### Have you read the CONTRIBUTING guide?
