[chore][receiver/azuremonitorreceiver] Move nslaughter to emeritus status (#43902)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description
Almost one year without contributions. I think @nslaughter you moved to
something else right?
Do you mind if we remove you to prevent from confusions in the review
process ?

**Edit** - Correcting myself, a move to Emeritus role is more
appropriate.
