Add Write permission for opentelemetry-cpp-contrib

[TomRoSystems]

Hi,

We are planning to start releasing https://github.com/open-telemetry/opentelemetry-cpp-contrib for instrumenting httpd (Apache) and NGINX.

Would it be possible to give Write permission on this repo for users:
@TomRoSystems and @seemk

to help with open-telemetry/opentelemetry-cpp-contrib#11 ?

@TomRoSystems is part of @open-telemetry/cpp-contrib-approvers and should have Write permissions

I have added @open-telemetry/cpp-contrib-approvers to have Write permissions to the repo and @open-telemetry/cpp-contrib-maintainers to have Maintain permissions. For some reason only @open-telemetry/cpp-approvers and @open-telemetry/cpp-maintainers were listed there before:

We also have triager role, if one needs to be created for cpp-contrib, let me know.

Please re-open ticket if more permissions needs fixing
