Fix anchor link generation and add example usage to README builder

[Copilot]

The README builder generated non-functional anchor links using file paths (e.g., #.github/workflows/Package-Publish.yml) and lacked usage examples.

Changes

• Created toAnchorId() utility - Converts text to markdown-compliant anchor IDs (lowercase, special chars → hyphens)
• Fixed glossary links - Use toAnchorId(name) instead of raw file paths
• Fixed item headers - Match glossary anchors using same transformation
• Added example usage - Generate functional YAML examples for workflows and actions
  • Workflows: Complete job definition with uses and with blocks
  • Actions: Step definition with proper input syntax
  • Values: Defaults when available, else GitHub Actions expressions (${{ secrets.EXAMPLE_* }})

Example

Before:

#### [Node Package Publish](#.github/workflows/Package-Publish.yml)

After:

#### [Node Package Publish](#node-package-publish)

**Example Usage:**

    name: Example Workflow
    on:
      push:
        branches: [main]
    
    jobs:
      example:
        uses: Bracketed/Workflows/.github/workflows/Package-Publish.yml@main
        with:
          project-name: @${{ github.repository }}
          repository-owner: bracketed
          node-version: 23

Original prompt

Fix the anchor links in the readme builder so they work, and add in example usage to the builders so the readme is populated with functional and high quality data and design
