chore: drop unused PHP 8.2 and 8.3 test images

[loks0n]

composer.json already requires >=8.4.1, and docker-compose.yml defaults to PHP_VERSION=8.4, so Dockerfile.php-8.2 and Dockerfile.php-8.3 are dead files that no workflow or compose service references. Removing them.

No composer.json change needed here — the minimum is already above 8.4.

Greptile Summary

Removes obsolete Docker test images for unsupported PHP versions.

• Deletes the PHP 8.2 test-image Dockerfile.
• Deletes the PHP 8.3 test-image Dockerfile.
• Retains alignment with the PHP 8.4.1 minimum requirement and the PHP 8.4/8.5 CI matrix.

Confidence Score: 5/5

The PR appears safe to merge because current workflows and supported PHP versions do not rely on either deleted Dockerfile.

The package requires PHP 8.4.1 or newer, CI tests PHP 8.4 and 8.5, and no current repository workflow, script, service, or documentation directly references the removed PHP 8.2 or 8.3 images.

Important Files Changed

Filename	Overview
Dockerfile.php-8.2	Deletes an unreferenced test-image definition for PHP 8.2, which is below the package's supported PHP minimum.
Dockerfile.php-8.3	Deletes an unreferenced test-image definition for PHP 8.3, which is below the package's supported PHP minimum.
