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

[MariusStorhaug]

Description

This pull request significantly reduces and simplifies the documentation and metadata for the Build-PSModule GitHub Action, focusing on minimalism and removing detailed usage and implementation information.

Documentation simplification:

• The README.md file was almost entirely rewritten, removing all detailed explanations about supported module types, build steps, repository structure, manifest generation, and references. It now contains only a single line briefly describing the action and its relation to the PSModule framework.

Metadata cleanup:

• In action.yml, the action's name was simplified, and the branding section specifying the icon and color was removed to further streamline the action's metadata.
