Fix setting the configuration parameter in the apple test runner

[MaximLipnin]

This PR fixes a typo which prevented local test run for macatalyst release build due to the following error:

  XHarness command issued: apple test --app=/Users/maxim/dev/runtime/artifacts/bin/System.Security.SecureString.Tests/net7.0-Release/maccatalyst-arm64/AppBundle/System.Security.SecureString.Tests/-maccatalyst/System.Security.SecureString.Tests.app --targets=maccatalyst --xcode=/Applications/Xcode.app/Contents/Developer/../.. --output-directory=/Users/maxim/dev/runtime/artifacts/bin/System.Security.SecureString.Tests/net7.0-Release/maccatalyst-arm64/AppBundle/xharness-output
  info: Preparing run for maccatalyst

  fail: Failed to find Info.plist inside the app bundle at: '/Users/maxim/dev/runtime/artifacts/bin/System.Security.SecureString.Tests/net7.0-Release/maccatalyst-arm64/AppBundle/System.Security.SecureString.Tests/-maccatalyst/System.Security.SecureString.Tests.app/Contents/Info.plist'
  XHarness exit code: 79 (FAILED_TO_GET_BUNDLE_INFO)

It's because the app bundle path didn't contain config part (-maccatalyst instead of Release-maccatalyst)
