[exporter/datadog] Deprecate service and version settings (open-telemetry#8784)

* [exporter/datadog] Deprecate `service` and `version` settings

* Add changelog entry

* [exporter/datadog] Remove Service and Version from tests

* Address review comment

* Fix lint

* Bump to v0.49.0

This won't make it into v0.48.0, so I updated the deprecation and removal versions

* Update CHANGELOG
