Fix data URI download notification on Android 14+

[jpelgrom]

Summary

Fixes the following crash for data URI downloads (= automation traces from frontend) on Android 14+ devices. The download itself actually still works, but the app crashes when creating a notification to tell you it's done. I've done a quick check and think this is the only instance of an implicit intent that was mutable.
