fix: resolve Quote struct type mismatch and update tests (#103)

The rustfmt commit exposed an issue where the Quote struct in create-issue
was using String for author_url, but fetch-quote was returning Option<String>.

Changes:
- Updated Quote struct in create-issue to use Option<String> for author_url
- Fixed test template to use camelCase field names (authorUrl, authorDescription)
  instead of snake_case (author_url, author_description) to match serde renames
- Removed outdated assertion checking for subscribe_form which was removed
  from the template in a previous commit

All tests now pass.
