Add linux mint support

[lachsdachs]

Detect linuxmint distros and treat them as debian.

Question: how does ubuntu work here?
Mint is a Ubuntu fork and i have seen linuxmint strata getting the Ubuntu treatment in the upgrade_bedrock section, but i have not found any code that handles Ubuntu distros. But topgrade surely has support for the most popular distro of all, doesn't it? is it okay to treat ubuntu distros as debian?

It will be treated as Debian given it ID_LIKE field is debian: https://github.com/which-distro/os-release/blob/main/ubuntu/22.04

Thanks! I am actually surprised that this wasn't already supported by Topgrade:<

Does that mean that the distro detection logic is currently implemented in different places? Because that seems like a bad idea.

For example, the os-release thingy already has a linuxmint file with an 'ID-LIKE' set to "ubuntu", so it seems more sensible to just recursively check those files instead of implementing some of the decisions in topgrade and delegating others to os-release.

No, at least for now, I do want to build a Linux distro detection crate but hasn't started, so Topgrade still do the detection itself.

Even though Linux mint has its ID_LIKE set to ubuntu, it actually doesn't matter since it's unique ID is sufficient for detection.
