♻️ [Maintenance]: Repin Process-PSModule to released v6.1.0 to fix startup failure

The workflow was pinned to commit ea019351 on the feat/52-test-secrets branch
(PR #365). That PR was squash-merged and its branch deleted, so the commit is no
longer reachable from any ref and GitHub Actions can no longer resolve the
reusable workflow, causing every run to fail at startup with zero jobs. The
TestData secret interface from PR #365 shipped in v6.0.0, so repin to the current
release v6.1.0 (0d7a2f0b), whose workflow_call interface still accepts the
APIKey and TestData secrets this caller passes.
