DS-451 skill.md to convert to mdx

[cmcinnis-coveo]

Purpose

This pull request introduces two new Storybook-related skills for working with Plasma component documentation, along with detailed guidance and reference files for each.

1. converting-md-to-storybook-mdx, provides a step-by-step process for converting LLM-facing Markdown files into Storybook-ready MDX docs-only pages, including all formatting, placement, and escaping rules.
2. storybook-component-docs, outlines how to rewrite terse, machine-facing component docs into clear, human-readable usage guidelines, with strict rules for structure, style, and content completeness. Both skills include comprehensive instructions, checklists, and reference files to ensure consistency and quality.

Proposed changes

New skills:

• Added .github/skills/converting-md-to-storybook-mdx/SKILL.md, a skill for converting component .md files from packages/llms/src/components/ into MDX docs-only pages for the Plasma Storybook, with detailed process steps, formatting rules, and validation checklist.
• Added .github/skills/storybook-component-docs/SKILL.md, a skill for rewriting LLM-facing component docs into clear, human-readable usage guidelines for Storybook, including a page template, section-by-section rewrite rules, and completeness checklist.

Reference and formatting:

• Added .github/skills/converting-md-to-storybook-mdx/references/mdx-patterns.md, a reference covering required MDX structure, JSX escaping rules, handling of special links, GFM support, and troubleshooting for MDX docs.
• Added .github/skills/storybook-component-docs/references/expected-format.md, specifying the exact required format for the Content guidance section, including structure, subheading and bullet rules, and minimum coverage requirements.

@cmcinnis-coveo, before approving, I'd like to see a test run (conversions) using the skills.

@ksampsoncoveo Sure thing--I'm reworking some things right now in the skills and will include a demo before I mark it as ready for review. Thank you!
