Include MongoDB extension in official static binaries

Describe your feature request

Hi FrankenPHP Team,

First of all, thank you for this amazing project! It has significantly improved the developer experience for PHP and Laravel developers.

I would like to request the inclusion of the MongoDB extension in the official FrankenPHP static binaries and Docker images.

Why is this needed?

Popularity: Many modern PHP applications, especially those built with Laravel, use MongoDB as their primary or secondary database (NoSQL).

Complexity of Custom Builds: Currently, users who need MongoDB must build their own custom static binaries using static-php-cli, which is time-consuming and can be challenging for many developers.

Octane Compatibility: As FrankenPHP becomes a first-class citizen in Laravel Octane, having out-of-the-box support for MongoDB would make it a much more viable option for enterprise-scale applications.

Alternatives Considered: I have tried building a custom binary and using Docker with manual extension installation, but having it bundled officially would provide a much smoother onboarding experience for the community.

Would it be possible to add mongodb to the list of default extensions in the build process?

Thank you for your time and consideration!

The request concerns the default-extension build process for static binaries and Docker images; start by locating the configuration that defines those extensions. Confirm how MongoDB is built and bundled, then verify that the official binaries and images expose the extension as requested.
