[foxfooding] Availability for Linux is unclear

[plwt]

Describe the bug Mozilla VPN is listed as being available for Linux, but later in the signup, this is clarified as only being Ubuntu, with other distros having to build from code. Given the options for Snap, Flatpak, tarball, and even AppImage, to expect modern Linux users to build from code feels unfair and a barrier to entry.

What makes this confusing is that even though it states Ubuntu, the app works perfectly well enough on other distros such as Xubuntu, so stating Ubuntu is a bit limiting.

VPN version: 2.10.1 (2.10.1-jammy1)

Affected Platforms: Linux

Steps to reproduce: Follow through with normal installation for a Linux device following the SUMO KB article at https://support.mozilla.org/en-US/kb/how-install-mozilla-vpn-linux-computer

Expected result: Mozilla VPN is properly available for Linux, or the full list of distros that it is available for is listed.

Actual result: The messaging is for Ubuntu or build from code, neither feels quite right.

Additional notes: I am happy to help correct the KB article in Kitsune to try to straighten this out.

Flatpaks and Snaps provide additional safety due to running in a sandbox which is why I'd prefer to be able to install it through those methods as well
