CI: add PHP 8.5 to test matrix

[Copilot]

Extends the CI test matrix to include PHP 8.5 alongside existing versions.

Changes

• .github/workflows/ci.yml: adds '8.5' to the php-version matrix in testsuite-linux

No composer.json changes needed — the existing "php": ">=8.1" constraint already covers 8.5.

Original prompt

Create a PR that updates the CI (GitHub Actions workflows) to add PHP 8.5 to the test matrix.

Repository: LordSimal/cakephp-dump-sql

Requirements:

• Find the existing CI workflow(s) that run PHP tests (likely under .github/workflows/).
• Add PHP 8.5 to the PHP version matrix (or equivalent) alongside existing supported versions.
• Ensure the setup step uses shivammathur/setup-php (or the repo’s existing setup method) and that PHP 8.5 is included.
• If there are version constraints in composer.json/composer.lock that would prevent running on PHP 8.5, update constraints appropriately only if required for CI to run.
• Keep changes minimal and focused to CI.
• Update any README/support matrix only if the repo already documents supported PHP versions.

Validation:

• Ensure workflows remain valid YAML.
• Ensure the matrix includes php: '8.5' (quoted) and existing versions unchanged.

Output:

• Open a pull request with a clear title like "CI: add PHP 8.5" and describe what changed.
