check-version-bump: fall back to App.csproj when Directory.Build.props missing (#342)

Bootstrap fix for the v1.10.0 -> v1.11.0 release PR (#341). PR #315 (the
version-unification refactor that introduced Directory.Build.props)
landed on dev AFTER v1.10.0 was tagged, so main has never seen
Directory.Build.props — the main-side checkout step fails on Get-Content
with "Cannot find path".

Test-Path now prefers Directory.Build.props and falls back to the legacy
App.csproj location. Becomes dead code after #341 lands on main, but
harmless and self-documenting.
