It is needed because Plasma 5.20.4 is in the experimental suite, and not
yet in sid. See, for example:
https://packages.debian.org/sid/plasma-desktop
vs
https://packages.debian.org/experimental/plasma-desktop

In this case "adventurous" means you may encounter breakage, that you
understand the risks, and are nonetheless brave ;-) Please take your
time to consider carefully whether you can afford to break your GUI for
a couple of days. If you don't have a second system, it may be best to
test 5.20.4 from experimental in a VM, or wait for the upload to sid.
Don't forget that downgrading packages is not officially supported!
The only system I enable experimental for is a Core-2-duo Thinkpad that
I keep around for testing and as an emergency backup laptop. I'm not
very adventurous :-p

To enable the experimental suite, add this line to sources.list, or to a
file in sources.list.d:
deb http://deb.debian.org/debian experimental main
