remove zipkin from the conanfile.py due to my interpretation of the breaking changes of version 1.25.0 [CONFIGURATION] File configuration - remove zipkin

@Hailios

Thanks for reaching out.

There is some confusion here.

I am a maintainer of opentelemetry-cpp.

For clarity:

Zipkin is still supported in opentelemetry-cpp.

What is not supported, is to use zipkin from a yaml configuration file, which is a new feature known as "declarative configuration", see repository https://github.com/open-telemetry/opentelemetry-configuration.

So, it makes sense to keep zipkin here, for the time being.

Now, in the long term, be advised that zipkin is deprecated from the specifications, and will be removed later, but this will happen much later, not now.

See https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/sdk_exporters/zipkin.md

I reverted the changes to conanfile.py such that zipkin is left as it was. thanks!

I have signed the CLA multiple times by clicking on the failing CI check, using different computers with different browsers. check still fails. What should I do to get past the license/cla check?
