[rocprofiler-compute] Update pip version in workflow

[jbonnell-amd]

Motivation

We noticed that Ubuntu 22.04 runs were failing all tests due to missing pytest module.

Technical Details

• Update .github/workflows/rocprofiler-compute-continuous-integration.yml
  • Updated pip install step to show current pip version and perform a pip upgrade
    • Issue was with the default version of pip in 22.04 using an older version of pip that did not support the --break-system-packages argument
  • Update setup_env step to only add coverage and nightly label to CDash when on schedule, to support manual workflow_dispatch runs without overriding the nightly result
