For Fedora 43 final release, we need the 'release' of fedora-release to be -1 or higher. This stops pre-release warnings showing on some forms of the installer.

Proposing as a Final blocker per "A fedora-release package containing the correct names and information and a fedora-repos package containing the correct repository configuration for a final Fedora release must be present on release-blocking images and the appropriately versioned generic-release package must be available in the release repository" and "No notices or alerts about pre-release status may be shown as part of installation or critical path actions on release-blocking desktops" - https://fedoraproject.org/wiki/Fedora_43_Final_Release_Criteria#Pre-release_notices
