Update awscli to reflect that it now supports Python 3.12

[luckman212]

Summary

awscli has been updated to support Python 3.12. Despite being one of the most popular formulae, it is one of the last to still require python3.11, so would be good to remove this dependency.

• Original Formula: https://github.com/Homebrew/homebrew-core/blob/master/Formula/a/awscli.rb
• Upstream Python 3.12 support issue is now closed: V2 support for Python 3.12 aws/aws-cli#8342
• Fix note in CHANGELOG: https://github.com/aws/aws-cli/blob/ac98e5e7526627c069dd34c10a77324dc86a4169/CHANGELOG.rst?plain=1#L22

Test with version built from source

$ aws --version
aws-cli/2.17.52 Python/3.12.6 Darwin/24.0.0 source/arm64
