- Upgrade to v2.2:
* Small RR release. Seer now runs 'rr replay' internally.
* Fixed infinite loop when starting with RR mode.
* Reworked RR mode to directly run 'rr replay'.
No need to start a 'rr server' and connect to it.
* Fixed Source handling in source browser.
Qt5 mode was broken.
Qt6 works. Directory paths need a tailing "/*".
- Fix build for openSUSE 15.5.
Changed from the default gcc version (7) to gcc 12, since it
supports C++17.
- Remove doubly declared files in the spec, removing some warnings.
- Add missing "Group" information.
