add telemetry setup to test

[msarahan]

Description

This is a prototype implementation of https://github.com/rapidsai/build-infra/issues/139

The work that this builds on:

• Add otel wrapper gha-tools#118, which adds a shell wrapper that automatically creates spans for the commands that it wraps. It also uses the opentelemetry-instrument command to set up monkeypatching for supported Python libraries, if the command is python-based
• https://github.com/rapidsai/shared-workflows/tree/add-telemetry, which installs the gha-tools work from above and sets necessary environment variables. This is only done for the conda-cpp-build.yaml shared workflow at the time of submitting this PR.

The goal of this PR is to observe telemetry data sent from a GitHub Actions build triggered by this PR as a proof of concept. Once it all works, the remaining work is:

• merge Add otel wrapper gha-tools#118
• Move the opentelemetry-related install stuff in https://github.com/rapidsai/shared-workflows/compare/add-telemetry?expand=1#diff-ca6188672785b5d214aaac2bf77ce0528a48481b2a16b35aeb78ea877b2567bcR118-R125 into https://github.com/rapidsai/ci-imgs, and rebuild ci-imgs
• expand coverage to other shared workflows
• Incorporate the changes from this PR to other jobs and to other repos
