Avoid stale AzDO retry failure annotations

[Evangelink]

Summary

• report retry-enabled acceptance-test Azure DevOps annotations as warnings
• keep transient failures visible without leaving stale failed-test errors after a successful retry
• preserve genuine final failures through the test process exit code and published TRX results

Root cause

--report-azdo emits an irreversible ##vso[task.logissue type=error] as soon as an attempt fails. The retry orchestrator can later recover the test, but Azure DevOps retains the initial error annotation even though the final retry summary, exit code, and Tests tab are green.

Validation

• built Microsoft.Testing.Platform.Acceptance.IntegrationTests.csproj in Release
• confirmed the evaluated command line contains --report-azdo-severity warning
• completed three independent code-review passes with no actionable findings

🧵 Parallel-safety audit — PR #10456

Nothing audited here touches process-global state, shared filesystem paths, or [ResourceLock] / [DoNotParallelize] declarations. The only changed file is test/IntegrationTests/Microsoft.Testing.Platform.Acceptance.IntegrationTests/Microsoft.Testing.Platform.Acceptance.IntegrationTests.csproj, and its diff only adds a --report-azdo-severity warning CLI argument to TestingPlatformCommandLineArguments. This is not a .runsettings, testconfig.json, or assembly-attribute change and does not alter parallelization scope, workers, or resource locking for the project. No changed test methods, lifecycle members, or fixture code exist in this PR.

Nothing to flag for parallel-safety.
