Bug Description

After upgrade to Kubuntu 24.04 the Chromium browser (snap) freezes when typing text to address box.

*How to reproduce:*
1. Let's have Kubuntu 22.04
2. Let's have Chromium browser (snap) installed
3. Upgrade to Kubuntu 24.04
4. Install Chromium browsed (snap)

*What happens:*
Chromium browser freezes for tenth of seconds when typing text to address box.
At the same time the syslog is flooded with following errors:
`
2024-05-14T20:59:28.993184+02:00 XXX dbus-daemon[2187]: apparmor="DENIED" operation="dbus_method_call" bus="session" path="/com/canonical/menu/4200024" interface="com.canonical.dbusmenu" member="Event" name=":1.45" mask="receive" pid=3337 label="snap.chromium.chromium" peer_pid=2453 peer_label="plasmashell"
`

*What is expected:*
Chromium browser shall work without freezing the same way as in Kubuntu 22.04

Chromium browser about string: "Version 124.0.6367.155 (Official Build) snap (64-bit)"

This is probably happening because before 24.04 plasmashell was not confined, therefore it had the "unconfined" label. But now that it is confined, we need a rule to allow peer_label="plasmashell"
