`checkForTokenDefinitionsInWrongPath` rejects test fixtures on Windows

[MrLightspeed]

Summary

Running ./gradlew run on Windows fails because checkForTokenDefinitionsInWrongPath only whitelists paths that contain the hard-coded substring /test_tokens/. Windows paths use backslashes, so the guard misses src\test\resources\test_tokens and throws.

Steps to reproduce

1. Checkout master at e0794ee on Windows 11.
2. Ensure Java 17 is installed (Temurin 17.0.13+11).
3. Run gradlew.bat run inside the repo.

Actual result

> Task :run FAILED
There is a token definition file (0x1234...json) placed in a directory where it does not belong (C:\Users\me\tokens\src\test\resources\test_tokens)

The walk treats the Windows-absolute path as unknown because it looks for /test_tokens/.

Expected result

The guard should allow test fixtures regardless of platform path separator so Windows contributors can run the task successfully.
