Fix production synthetic monitoring

[ejsmith]

Summary

• make the production onboarding synthetic check locate the project-type selector by its accessible role and name instead of mutable instructional copy
• include the correct GitHub Actions run attempt in failure alert issue metadata

Root cause

Production Synthetic Monitoring runs the current main test suite against the deployed production version. The project setup copy changed from Select your project type. to Choose your project type. on main after production 8.6.2 was deployed, so the exact-copy assertion failed even though signup, organization creation, project creation, and the configure page all worked.

Verification

• npm run validate
• git diff --check
• inspected the failing run's Playwright results and DOM snapshot to confirm the project-type selector is present in production

Breaking changes

None.

Fixes #2371
