Elaborate on Run failed description (#7344)

## Summary of changes

Adds some words after `Run failed` when it shows up in the status

`Run failed, please investigate and/or retry this (if flake) via Azure
DevOps`

## Reason for change

Push toward looking at Azure DevOps for the failure and re-running /
re-trying from there as it likely isn't obvious that we use a different
CI/CD tool than other tracing libraries. And hopefully it'll help raise
awareness for flake / issues 🤷

## Implementation details

Added words

## Test coverage

No test

## Other details

to have one review from a team member, and one review from apm-dotnet.
Trivial changes do not require 2 reviews.
