fix: uBlue OS should be detected as FedoraImmutable (#1043)

* refactor(parse_os_release): Don't rely on specific `ID`s for Fedora Immutable

Instead match `ID=fedora` or `ID_LIKE=fedora` and decide wether or not
the distro is immutable by `VARIANT`.

* feat: add aurora,bluefin,coreos support

The `os_release`s came from the following images:

- ghcr.io/ublue-os/aurora:93f0fd9f20b3
- ghcr.io/ublue-os/bluefin:5d37394a5d4b
- ghcr.io/ublue-os/ucore:63cd1200c344

* fix: bazzite should be detected as FedoraImmutable

* squash me: cargo fmt
