EcsResource: Record log group without trailing :*

Both with and without trailing `:*` are valid formats but there is a bug in the OpenTelementry collector which can’t handle the trailing `:*` (for now) (see open-telemetry/opentelemetry-collector-contrib#13702)

So remove addition of the trailing `:*` for now.
