mintinstall: add description of what a Flatpak is

[ssspace]

New users probably never heard of Flatpaks. To make it easier for them, the software store could have a short description, some ideas:

1 - Put an 'Alt text' so when the user hover the cursor over the Flatpak button, it shows the description



2 - Add the short description to the top of Flatpak page, after the word Flatpak or below it



Or both places(1 and 2 combined).

The description should be short, just to give the user a glimpse of what a Flatpak is about, a single line of text like:
"Flatpaks are applications with the latest version."

More ideas are welcome, thank you.

Good idea. Maybe also a caution: Flatpaks can cause lots of data traffic because of frequent updates, and can take up lots of disk space.

Should I post this idea on https://community.linuxmint.com/idea/welcome ?
I don't know if the developers follow this area of the forum.
