Add ArthurSens as a codeowner for prometheus exporters (#36475)

#### Description

Add @ArthurSens as a codeowner for the prometheus exporters and
prometheus translator. He has been an active contributor and reviewer of
changes to these components, and has shown good judgement in that
regard. He is also active in related efforts (OTLP support, PRW 2.0
support) in the prometheus server.

Thanks for the contributions @ArthurSens!
