Update examples.md for more realism (#332)

## Summary
- Updates all server.json examples to use `io.github` namespace instead
of `com.github`
- Fixes validator test case to use proper domain format
- Aligns with standard reverse domain name convention for GitHub-hosted
projects

This change improves consistency across documentation examples and
follows established naming conventions.
