Support eu-south-2 (Spain) region

[kevincerro]

I encountered that eu-south-2 region was not available when using Bref CDK PhpFpmFunction construct.
The bref runtime version is available as shown in https://runtimes.bref.sh/?region=eu-south-2&version=2.4.10

const phpFpm = new PhpFpmFunction(this, 'api', {
    phpVersion: '8.3',
});
