Missing DebugImage running on Mono in CI

[jamescrosswell]

After bumping Verify.Xunit from version 22.11.4 to version 26.6.0 the Sentry.NLog.Tests.IntegrationTests.Simple verification fails when run on Mono in CI.

See:

• Bumped Verify.Xunit to version 26.6.0 #3821

That change results in a missing a debug image in test/Sentry.NLog.Tests/IntegrationTests.Simple.Mono4_0.verified.txt.

Oddly the debug image is only missing in CI. When I run this test on my Mac locally, it passes.

Here's the diff on CI when running this test on macos-15 (arm64) and ubuntu (x64)
