DOCS-1601 - Remove accordion tags from FAQ sections and update style guide

[JV0812]

Purpose of this pull request

This PR removes <details> and <summary> accordion tags from FAQ sections to improve accessibility, SEO, and AI citation capabilities. It also updates the style guide with comprehensive guidance on when to use (and when NOT to use) collapsible sections.

Summary

Removed accordion tags from 7 documentation files containing FAQ sections (67 total accordion items). FAQ content is now displayed using bold question headings followed by visible answers. This change ensures FAQ content is immediately visible, scannable, and properly indexed by search engines and AI tools.

Updated the contributing style guide with:

• Clear table-based DO/DON'T guidelines for collapsible sections
• GEO (Generative Engine Optimization) principles documentation
• AI citation failure explanation for hidden content
• Title attribute requirement for accessibility
• Proper FAQ formatting examples

What changed

FAQ Documentation (7 files, 67 accordions removed):

• docs/search/mobot.md (24 items)
• docs/api/mcp-server.md (3 items)
• docs/get-started/sumo-logic-ui.md (6 items)
• docs/get-started/ai-machine-learning.md (11 items)

• docs/send-data/hosted-collectors/cloud-to-cloud-integration-framework/universal-connector-source.md (13 items)

Style Guide:

• Added table with 10 use cases showing when to use/not use <details> tags
• Documented GEO principles and AI citation impacts
• Added warning callout about FAQ/troubleshooting content
• Added title attribute requirement for <details> tags
• Provided proper FAQ formatting example

Why this change matters

1. GEO Compliance: Hidden content negatively impacts Generative Engine Optimization and search visibility
2. AI Citation: AI tools and search engines cannot properly cite content hidden inside accordion components
3. Accessibility: FAQ content must be immediately visible and scannable for all users
4. User Experience: Eliminates friction of clicking to reveal FAQ answers

Testing Plan

• Local build verified at http://localhost:3000/
• Reviewed all 7 FAQ pages for proper display
• Verified style guide table renders correctly
• Confirmed no broken links or formatting issues
• Checked that remaining <details> tags (code samples, installation methods) are properly used
