Bug fixes for AppImage Installer

Alfons reported that in the "Other" category, the "Online Information" button didn't work. Fixed.

Forum member Airdale reported liking Ungoogled Chromium and looked forward to the update feature. I replied that cannot update it:

I have fixed that also; however, do have a problem with updating at some repositories, so have had to hard-code to download just one version. Last night I discovered this:

https://github.com/dvershinin/lastversion

Works great:

# lastversion https://github.com/clickot/ungoogled-chromium-binaries
111.0.5563.111.1
# lastversion --assets --filter '\.[Aa]pp[Ii]mage$' https://github.com/clickot/ungoogled-chromium-binaries
https://github.com/clickot/ungoogled-chromium-binaries/releases/download/111.0.5563.111-1/ungoogled-chromium_111.0.5563.111-1.1.AppImage

...very nice! Not sure if I will use it though, as it requires rather a lot of dependencies. Will look around a bit more, see if there are any other alternatives.

EDIT:
No, lastversion is not up to the job:

# lastversion https://github.com/probonopd/Zoom.AppImage
CRITICAL: No release was found
# lastversion --assets https://github.com/probonopd/Zoom.AppImage
# 

I will stay with my script /usr/local/appimage/github-find-latest-ver
