Installation docs: old versions

[JonLevin25]

Summary

Installation instructions for Linux (https://docs.ombi.app/guides/installation/#linux-systems)
propose a few methods to install Ombi v4.
I've tried installing using the develop v4 method, and the PackageCloud v4 method.

Both of which provide an outdated version from apt (v4.20.1)

After installation, the WebUI "About" section shows an upgrade available (v4.46.4).
But it's only download links to tarballs... no instructions on how to upgrade.

The docs also have a note Note 3: Apt-Key has been deprecated in Ubuntu 21.xx onwards. Use the v4 (21.xx) method below for this OS.

Which hint that there is another installation method... But I couldn't find it.

If the apt repo is not maintained I would suggest perhaps adding a section on how to manually install from GitHub releases, and/or instructions on how to upgrade. Thanks :)

No it is not, I just don’t really maintain those ways of installing as my knowledge of those distributions is very limited

Could we at least get a one-off update of how to install it since apt-key is deprecated?
