KeePassXC shows a pop up window with the text:

A new version of KeePassXC is available!
KeePassXC 2.6.2 is now available - you have 2.6.1

Version-Release number of selected component (if applicable):
2.6.1

How reproducible:
Happens when there is a new KeePassXC version released upstream


Steps to Reproduce:
1. Install KeePassXC (via dnf)
2. Wait until upstream releases a new version that is not yet provided by dnf.
