fix(docs): remove broken STYLE_GUIDE.md link and fix docs site URL in README

[zeemy23]

Summary

Fixes two small issues in README.md:

1. Broken link removed — The Contributing section referenced [Style Guide](STYLE_GUIDE.md), but STYLE_GUIDE.md does not exist in the repository (returns 404). Removed the dangling reference.

2. Documentation URL corrected — The "Live Documentation" quick link and the "About This Repository" link both pointed to https://opentdf.io, but the actual documentation site domain is docs.opentdf.io (confirmed via static/CNAME). Updated both URLs to https://docs.opentdf.io.

What changed

• Removed the For style guidelines, please refer to our [Style Guide](STYLE_GUIDE.md). line
• Changed https://opentdf.io → https://docs.opentdf.io in two places

Test plan

• Verify the "Live Documentation" link resolves correctly
• Verify no remaining references to STYLE_GUIDE.md
• Build passes (npm run build)

Summary by CodeRabbit

• Documentation
  • Updated documentation links to reflect current resources.

🐰 A rabbit hops through docs so bright,
Links now point to URLs right,
From opentdf to docs subdomain,
Clarity flows like morning rain,

Code Review

This pull request updates the documentation URL to the correct subdomain and removes a link to a missing style guide. Feedback was provided to update remaining references to style standards to maintain consistency for contributors.

[gemini-code-assist]

The removal of the STYLE_GUIDE.md link is correct as the file is missing. However, the list item above (line 32) still references "Style and formatting standards". If these standards are now primarily covered by the Vale configuration or the upstream contributing guide, it would be beneficial to update the list or add a brief mention of where these standards can now be found to avoid ambiguity for new contributors.
