.service suffix duplicated in D-Bus service file

[aklapper]

Running hexchat-2.16.1-2.fc38 on Fedora 38, journalctl output says:
dbus-broker-launch[1439]: Ignoring duplicate name 'org.hexchat.service' in service file '/usr/share//dbus-1/services/org.hexchat.service.service'

The corresponding upstream file is at https://github.com/hexchat/hexchat/blob/master/src/common/dbus/org.hexchat.service.service.in

Content of the local file /usr/share/dbus-1/services/org.hexchat.service.service in Fedora 38 is:

[D-BUS Service]
Name=org.hexchat.service
Exec=/usr/bin/hexchat

Obviously the filename should not include twice the string .service, and its content should have the line Name=org.hexchat instead.

Fedora could define -Ddbus-service-use-appid=true to use a more reasonable service name. It is opt-in because it is a public API break.
