Bump Process-PSModule to v5 (#6)

This pull request updates the workflow reference in the
`.github/workflows/Process-PSModule.yml` file to use a newer version of
the shared workflow.

- Updated the `Process-PSModule` job to use the `v5` version of the
shared workflow instead of the previous `001-unified-workflow`
reference.
