New libmbim, libqmi, and modemmanager in Debian experimental

[Martin]

Dear modemmanager community,

libmbim 1.23.900-0.1, libqmi 1.25.900-0.1, and modemmanager
1.13.900-0.1 are now available in Debian experimental. It would
be helpful for both modemmanager and Debian, if people could try
the packages before the planned releases.

If you happen to run Debian testing or Debian unstable, you can
enjoy the release candidates by:

$ echo deb https://deb.debian.org/debian/ experimental main \
  | sudo tee /etc/apt/sources.list.d/experimental.list
$ sudo apt update
$ sudo apt install -t experimental modemmanager

Thanks for any help!
