⚙️ [Maintenance]: Repository automation now uses Process-PSModule v6.1.7 (#39)

Repository automation now uses Process-PSModule v6.1.7. This keeps the
module workflow aligned with the latest shared Process-PSModule updates
without changing the module's shipped behavior.

## Changed: Repository automation uses Process-PSModule v6.1.7

The reusable Process-PSModule workflow reference is updated from v6.1.4
to v6.1.7. This affects build, test, and publish automation for the
repository, but it does not change the module's public commands or
runtime behavior.

## Technical Details

- Updated `.github/workflows/Process-PSModule.yml` to point at
`PSModule/Process-PSModule/.github/workflows/workflow.yml@8b1a2617a0686ceaeadc6fa8e2f395edda93cc6d`
(`v6.1.7`) instead of `v6.1.4`.
- Local validation: `Invoke-Pester -Path tests -Output Minimal` passed
after reproducing the workflow test setup by seeding `TEST_SECRET` and
`TEST_VARIABLE` and dot-sourcing functions from `src/functions/public`.
