Repoint comments to xunit-reqnroll as canonical reference

Per the spirit of recent review feedback that all sample repos should
look + work similarly, treat xunit-reqnroll-playwright-browserstack as
the closest precedent for this sample (vs csharp-playwright-browserstack,
the older reference). Refreshes inline comments to point at the right
hooks/scenario in xunit-reqnroll. No behavioural changes.
