fix: correct Docusaurus edit URL path (smart-mcp-proxy#200)

The editUrl was pointing to /docs/ but docs are at repo root.
Docusaurus appends 'docs/' to the editUrl, so the base URL should be
just the repo root without any extra path.

Changed editUrl from '/docs/' to '/' so paths become correct:
- Before: docs/docs/getting-started/installation.md (404)
- After: docs/getting-started/installation.md (correct)
