Thank you, Cliff!

I finally managed to download all the RPMs (manually, one by one) and
update them and reboot. (Is there a way to have a repository that I can
use 'zypper up --from'?)

Now my system has the following:

libply-boot-client5-0.9.5+git20201026+53c83cc-332.10.x86_64
libply-splash-core5-0.9.5+git20201026+53c83cc-332.10.x86_64

libply5-0.9.5+git20201026+53c83cc-332.10.x86_64

The initial password screen in Grub now again looks like
https://bugzilla.suse.com/attachment.cgi?id=847968
not like the much bigger font I shared in comment #16.

The later screen (attachment "Screenshot of the startup screen")
looks unchanged, i.e., the small text, that is sliced horizontally,
to half to the right, bottom half to the left, still is there.
