[i18n] Adding Italian translations

[fellyph]

This pull request adds new Italian translations for the WordPress Playground documentation, specifically for the "Contributing" section. It introduces three new files: a category label, a comprehensive code contribution guide, and documentation for contributor badges. These additions provide Italian-speaking contributors with localized guidelines and information on how to participate and be recognized within the project.

New Italian documentation:

• Contributing section label:

  • Added _category_.json to label the section as "Contribuire".

• Code contribution guidelines:

  • Added code.md with detailed instructions on contributing code, running a local development environment, debugging, and best practices, all translated into Italian.
  • Added coding-standards.md outlining coding principles, error message standards, API design, and blueprint guidelines, fully localized.

• Contributor recognition:

  • Added contributor-badge.md explaining the criteria and process for obtaining the WordPress Playground Contributor and Team badges, including instructions and visual examples, in Italian.
