🩹 [Patch]: Bump Process-PSModule to v5 (#28)

## Description

This pull request updates the repository's GitHub Actions workflow
configuration by consolidating and simplifying workflow files, updating
workflow versions, and removing unused linter and nightly run workflows.
The changes focus on streamlining CI/CD processes and aligning with the
latest standards for the `Process-PSModule` workflow.

**Workflow configuration updates:**

* Updated `.github/workflows/Process-PSModule.yml` to add
`workflow_dispatch` and scheduled (`cron`) triggers, enabling manual and
nightly runs in addition to pull request triggers.
* Upgraded the referenced version of the `Process-PSModule` reusable
workflow from `v4` to `v5` for improved compatibility and features.
* Added a new `.github/PSModule.yml` configuration file to set up code
coverage targets and provide workflow customization options.

**Workflow cleanup and removal:**

* Removed the `.github/workflows/Linter.yml` workflow and its associated
linter configuration `.github/linters/.jscpd.json`, indicating that
linting is no longer run as part of CI.

* Deleted the `.github/workflows/Nightly-Run.yml` workflow in favor of
integrating nightly scheduling directly into the main workflow.
