Add more Logging for cloud functional test workflow (radius-project#7885

)

# Description

There have been some unexpected runs for the cloud-functional-tests
which fail. A recent instance was on 9/1/2024, with multiple runs, some
of which were against commits that were already merged into main 2 days
ago.
eg. https://github.com/radius-project/radius/actions/runs/10648348010

This PR adds additional logging to capture the values of multiple
fields, allowing us to determine the correct filter conditions for
triggering the workflow when event = workflow_run.

Note: This specific event may also have been related to a GitHub outage
that happened the same week but nonetheless, similar failed runs have
been recorded earlier.

## Type of change
- This pull request fixes a bug in Radius and has an approved issue
radius-project#7782
