feat: Add support for specifiying Lambda `architectures` to allow ARM based functions

[bryantbiggs]

Description

• Add attribute architectures to allow users to opt into using ARM based functions
• Update default Python runtime from 3.7 to 3.9 - 3.7 is not supported by ARM functions, only 3.8-3.9 are and the code is compatible across all 3 runtimes so upgrading to the latest
• Update S3 bucket module to latest which pins provider at v3.x; next update will be when new S3 module is released to support provider v4.x

Motivation and Context

• Allow users to deploy ARM based functions for lower operating costs

How Has This Been Tested?

• Yes; tested using complete example
