pkg.requires.os.release = python3-pyright breaks CI on Kali Linux. It
is present in the janware repos, but using those would cross a line:
jw-pkg must be buildable from the base repositories alone, so don't make
pyright mandatory for Debian, because that pulls it in for Kali, too.
Ironically, the Debian repo provides it. Which makes it obvious that
we will need another entry in the os cascade for Debian proper to
allow pulling in such packages on Debian.
