update appimage runtime

[Drsheppard01]

this will help alpine, nix, void and other users to use appimage

This pr also raises the question of the usefulness of other libraries such as gconf

Looks good, the only thing I'm not sure is why are the runtimes are also being added manually and not just changing the url to the type2-runtime repo?

If I understand correctly, first the makefile is executed, then the reference is changed and a release of this binary is made, and after that electron-builder uses the binaries

FWIW, I'm attempting to redo the entire release process of electron-builder-binaries so that it fetches or compiles assets during CI/CD and publishes to combined releases with has

As part of that, it'll be updating the appimage runtimes, so I think we can close this PR.
It does sound like runtime may no longer be needed though? I might just need to migrate to appimagetool?

Additional context:
I'm looking to remove as many pre-committed binaries from the repo as possible and instead do fresh compilations/downloads in ephemeral Github runners. Previously, all releases were handled by develar, assets compiled locally on a laptop, and then committed/released directly from the local computer. This is not a proper pipeline, nor considered secure by industry standards, so I'm attempting to standardize/secure the repo's pipeline BEFORE pushing a new release with artifacts with updated versions.

Yes unless electron-builder has something to build offline, the runtimes don't need to be included.

Nifty! I'll add to my to-do list to investigate migrating to appimagetool then.

electron-builder can't do everything offline unless the electron-builder-binaries cache is already populated with all necessary tools; not sure if building offline is a hard requirement since it's highly unlikely electron-builder and all node_modules are committed directly to the project's repo.
