arm functions use wrong layer

[franco-bildungsfinder]

Hi

Happy new year! It's me again :-).

I tried to use arm functions, but the lambdas are created with the x86 layers.

What I tried:

new PhpFpmFunction(this, 'Function',{
           .....
            phpVersion: '8.1',
            architecture: Architecture.ARM_64,
});

and the created lambda has the x86 layer.

I think the problem is that in in defaults.ts platform is hardcoded to x86 and in PhpFunction.ts (https://github.com/brefphp/constructs/blob/main/src/function/PhpFunction.ts#L47) the value from the defaults.ts is used to lookup the layer ARN without allowing to overwrite it.
Also the "official" property in FunctionProps in the cdk is called architecture (https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.FunctionProps.html#architecture). Would probably make sense to use the same name here.

The good news is, if I use the above code and manually change the layer to the arm layer, things work perfectly.

Oh good point, thank you for the details! I'll take a look at that!
