nixos/geoclue2: set default location service to beaconDB (#391845)

  [is removed](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c01f664e4ca210823b7594b50669bbd9b0a3c3b0)

  in Linux 6.13.

- `services.geoclue2` now uses [beaconDB](https://beacondb.net/) as a default geolocation service, replacing Mozilla Location Services which was [retired in June 2024](https://github.com/mozilla/ichnaea/issues/2065).

- `authelia` version 4.39.0 has made some changes which deprecate older configurations.

  They are still expected to be working until future version 5.0.0, but will generate warnings in logs.

  Read the [release notes](https://www.authelia.com/blog/4.39-release-notes/) for human readable summaries of the changes.
