Update tests to handle filelock 3.21.0+ behavior change

Filelock 3.21.0 introduced automatic deletion of lock files on release
for Unix systems. Updated test expectations to not include .lock file
on non-Windows platforms, as the lock file is now cleaned up after
release. This aligns with standard Unix lock file behavior.
