Switch to type2runtime by default from old AppImageKit runtimes.

Please switch to the new version at
https://github.com/AppImage/appimagetool/releases/tag/continuous
This version is merely kept around for legacy compatibility. It is not recommended to be used anymore and is no longer actively supported.

We don't need to move into anything, only change the defaults. Technically, there's type2runtime config property that basically makes it to use the same runtime as new appimagetool. And ReForged principles are not to rely on toolkits made specifically to package to the specific format if possible, and rather handle packaging on its own from scratch. Thus, maker-appimage is kinda appimagetool reimplementation in JavaScript on its own, only relying on system-wide mksquashfs.

If this is true, is it possible to use type2-runtime by default instead of optional?

Sure, I'll probably also consider a bit different runtime source management (there's way more runtimes in the internet, and even some alternatives to AppImages that aim to become cross-platform) and possibly to drop AppRun entirely, I think symlink to bin is enough for Electron apps anyway. The problem are still hash checks, since those ReForged had hard-coded before and with the continuous release cycle, it'll be troublesome to keep it that way… I mean, I can always rely on checksums and error corrections within the protocols entirely.

Now I'm looking forward to the release. I'm sure it will help the whole community. Thank you for your contribution to the AppImage ecosystem
