fix(docs): allow localhost links in link validator

Add errorOnLocalLinks: false to starlight-links-validator configuration
to permit localhost URLs in development documentation.

Root cause: The notes/build/rolldown-workers-incompatibility.md file
contains a reference to http://localhost:8787 as part of testing
instructions. This is valid for development notes but was being flagged
by the link validator.

This configuration aligns with typical development documentation patterns
where localhost references are acceptable for testing and preview
instructions.

Fixes link validation error:
- Found 1 invalid link in 1 file.
- notes/build/rolldown-workers-incompatibility/
- http://localhost:8787 - local link
