Remove tigrannajaryan as Maintainer (#8128)
Remove tigrannajaryan as Maintainer (#8128)

I am no longer able to allocate time to be a maintainer of the Collector contrib
due to focusing on other parts of OpenTelemetry.

I will continue fulfilling a maintainer responsibility of the Collector core.

Thank you all, it was a pleasure working with you! And who knows, I may be able to
return sometime in the future.

I am moving myself to the Emeritus section according to the rules introduced in
https://github.com/open-telemetry/community/pull/961

P.S. We should add other previous approvers/maintainers in the Emeritus section.
