[ Impact ]

The modemmanager v1.20.0 doesn't have Quectel EM061K-GL/EM160/RM520N PID information,
and the modemmanger won't recognize these WWAN modems on some next-gen Lenovo laptops.
(lp: #2045276)

[ Test Plan ]

Under Jammy environment, with latest linux-oem kernel installed,
check output of `mmcli -L` to see if the modems are properly recognized.

Modems to check:
- EM061K-GL
- EM160
- EM160

[ Where problems could occur ]

EM160R-GL(1.22.0):
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1059/diffs

EM061K-GL(1.22.0):
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1057/diffs

RM520N-GL(1.22.0):
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1052/diffs
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1077/diffs

All these changes are merged, and they only introduce new PIDs for
initial supports, which do not affect existing ones.

Noble contains these changes, so, only SRU jammy.
