There's a merged pull request on the void-packages repository

Xfce4: cleanup
https://github.com/void-linux/void-packages/pull/20696

Description:
* ignore releases for all xfce components that use an odd minor version for development releases (most of https://git.xfce.org/xfce/ ). I'm tired of people PR version bumps for development releases.
* remove two abandoned packages
* downgrade [xfce4-power-manager](https://github.com/void-linux/void-packages/pull/19971) to stable release

TODO:
* [x] please verify I didn't screw up with `reverts=`
