LLVM PPA: Script source availability

[Whisperity]

In addition: I am specifically looking for the people/community
maintaining the "nightly" APT.LLVM.ORG and **not** the official
release Debian package repository.
I might be sending mails to the wrong place?

I was working off of this information:

> $ apt-cache show clang-12 | grep 'Version\|Maintainer'

> Maintainer: LLVM Packaging Team <pkg-llvm-team at lists.alioth.debian.org>
