Describe the bug
Links in the "About Timeshift-gtk" window do not open

To Reproduce
We open Timeshift, select "About the application" from the menu, the "About Timeshift-gtk" window opens, we click on any link in this window or, by hovering the cursor over and right-clicking on this link, select "Open link" and nothing happens, despite the default browser being open, in my case Firefox.

Expected behavior
When you left-click on a link, a browser should open with a tab for that link, or when you select "Open Link," a browser should open with a tab for that link.
