🩹 [Patch]: Move documentation and link to Process-PSModule

[MariusStorhaug]

Description

This pull request primarily cleans up and simplifies the documentation and metadata for the Test-PSModule GitHub Action. The most significant changes are the removal of detailed usage instructions and specifications from the README.md, and a simplification of the action's metadata in action.yml.

Documentation and metadata simplification:

• The README.md file has been drastically reduced, removing all detailed setup instructions, usage explanations, input/output tables, and specification details, leaving only a single-line description and a link to the PSModule framework.
• The action.yml file has been simplified by removing the branding section and slightly adjusting the action name, making the metadata more concise.
