+  `service.name` and `service.version` attributes were mistakenly controlled by `heroku.app.name` and
+  `heroku.release.version` options under `resource_attributes` configuration introduced in 0.81.0. 
+  This PR fixes the issue by using the correct config options named the same as the attributes.
