nixos/syncthing: fix path setting for versioning

Syncthing config XML uses `fsPath` setting for specifying the path to the versioning folder. This commit adds `services.syncthing.folders.<name>.versioning.fsPath` option to enable this functionality declaratively. Previously, `versioning.params.versionsPath` was used, which doesn't work.
