🩹 [Patch]: Replace secrets inheritance with explicit secret passing (#137)

Improves workflow security by replacing unconditional `secrets: inherit`
with explicit secret passing in the Process-PSModule workflow. This
follows the principle of least privilege by only passing the required
`APIKey` secret instead of exposing all repository secrets to the
reusable workflow.

- Fixes #136

## Changes

1. **Updated `.github/workflows/Process-PSModule.yml`**: Changed from
`secrets: inherit` to explicitly passing only the required `APIKey`
secret using `APIKey: ${{ secrets.APIKey }}`.

## Benefits

- Reduces risk of unintended secret exposure to reusable workflows
- Follows GitHub Actions security best practices
- Addresses zizmor security linting warnings
- No functional changes - the workflow continues to operate identically
