Bug#922155: [Pkg-matrix-maintainers] ITP: matrix-archive-keyring -- OpenPGP archive key for the Matrix.org package repository

[Linda Lapinlampi]

I believe this package is ready for Debian now. I'm looking for a
sponsor now; more details in a RFS issue to follow.

Thanks to the few people in the #debian-matrix:matrix.org room for
testing experimental pre-releases.
