Add support for `ubuntu-based` systems

[ochaplashkin]

I'm like a PopOS ubuntu-based system user, I want the script to work for me.

The script prints a message that my system is not supported:

pc@workstation:~$ ./installer.sh
Unfortunately, your operating system is not supported by this script.

/etc/os-release contain follow data:

NAME="Pop!_OS"
VERSION="22.04 LTS" <--
ID=pop
ID_LIKE="ubuntu debian" <--
PRETTY_NAME="Pop!_OS 22.04 LTS"
VERSION_ID="22.04"
HOME_URL="https://pop.system76.com"
SUPPORT_URL="https://support.system76.com"
BUG_REPORT_URL="https://github.com/pop-os/pop/issues"
PRIVACY_POLICY_URL="https://system76.com/privacy"
VERSION_CODENAME=jammy
UBUNTU_CODENAME=jammy
LOGO=distributor-logo-pop-os

Same, [[ $os_like = "ubuntu" ]] should be changed to [[ $os_like == *"ubuntu"* ]] in installer.sh
