feat: Introducing deb and rpm auto-updates

[mmaietta]

[Draft]
Utilizes GUI-based sudo for installation which is pulled via which gksudo || which kdesudo || which pkexec || which beesu and executed using /bin/bash -c in order to coalesce all commands under a single sudo prompt
Deb is fairly straightforward and evals to this:

`which dnf || which yum` -i path-to-update.deb || apt-get install --fix-broken -y

Rpm requires one of these package managers available: zypper, dnf, yum

zypper -y remove AppName; zypper -y install path-to-update.rpm

js is optimized, but the shell cmd basically is:

`which dnf || which yum` remove -y AppName;
`which dnf || which yum` clean --all;
`which dnf || which yum` --no-refresh install --allow-unsigned-rpm -y -f path-to-update.rpm

Testing still in progress on Ubuntu 14/18/20/22 and Fedora 32. No clue what else to test on, suggestions would be appreciated

Things I could use help/verification on:

• idk if --allow-unsigned-rpm is a good idea, but that's what I use in my home project.
• are those enough package managers to cover?

Note: This would need to go through a significant alpha version stage for electron-builder

@develar what are your thoughts on this?

I would love to configure this for my app but there's (seemingly) no documentation on how to set up autoupdating for .deb. What are the steps needed to support and test this?

[mmaietta]

@Kilian it should be the exact same setup as when using AppImage, just need to add deb as a target in electron-builder config.
