[docs] Adding WASM PHP modules page

[fellyph]

This pull request updates the documentation for PHP.wasm in both English and Spanish, clarifying the package structure and usage for Node.js and web environments. It introduces a new architecture page detailing the separation of the shared API, platform adapters, and version-specific binaries, and aligns the Spanish translations with these updates.

Documentation improvements and new content:

• Added a new page, 06-php-wasm-packages.md, explaining the PHP.wasm package layers, including the shared API (@php-wasm/universal), platform adapters (@php-wasm/node, @php-wasm/web), and version-specific binaries, with guidance on when to use each approach.
• Updated English docs for Node.js usage to clarify the distinction between platform adapters and version-specific packages, and to provide instructions for minimal installation size and direct loading of a single PHP version. [1] [2]
• Improved the architecture overview to reference the new PHP.wasm package structure and link to the new documentation. [1] [2]

Spanish and Portuguese translation alignment:

• Updated the Spanish and Portuguese Node.js usage guide to match the new English documentation, including improved explanations, code comments, and instructions for both platform adapter and direct single-version usage.
• Added a new Spanish and Portuguese architecture overview page, mirroring the updated English content and providing localized explanations of the PHP.wasm package structure and project tooling.
