Support PHP 8.1 for ARM layers

Follow-up of brefphp/aws-lambda-layers#40

Ref #1043

The PHP 8.1 ARM FPM layers appear to be missing cURL so don't actually run correctly at the moment:

Fatal error: Uncaught Error: Call to undefined function Bref\Runtime\curl_init() in /opt/bref/php-fpm-runtime/vendor/bref/bref/src/Runtime/LambdaRuntime.php:111

Oh interesting, it seems our tests are not catching it: https://github.com/brefphp/aws-lambda-layers/blob/main/tests/test_2_extensions.php#L8

I'll investigate that, thanks @aran112000!

@aran112000 the new beta was kind of broken actually, I pushed a new beta to fix this (tested ARM PHP 8.1): https://github.com/brefphp/bref/releases/tag/2.0.0-beta3

Thank you!

You're a star - thanks so much for diagnosing and getting a new release pushed out so quickly!! Just rolled out an internal service on it as a test and it's working perfectly (PHP 8.1 on Graviton) 🚀

That is awesome feedback, thank you for sharing!

The performance of these new ARM layers on Bref 2 is insane! We've upgraded another workload this afternoon and here are the performance results looking at the total Lambda duration (Orange: AVG, Blue: MIN):

If you can't guess, the changes rolled out 13:35.

What's more crazy, is we reduced the allocated memory from 512 to 360 as well! 🚀

@aran112000 wooow that's awesome!
