Install awscli v2 bundle when possible

[cartermckinnon]

Description of changes:

This installs the latest awscli v2 bundle when possible, as the version available in the AL yum repos generally lags behind. It also includes the version of the awscli in the binaries section of the version-info.json file, because the bundle wouldn't appear in the packages section.

Testing Done

In us-west-2, I can see that the v2 bundle is installed:

and the version is present in version-info.json:

For anyone who found that $sudo aws don't work after updating node to v20221112 or later version,

$ sudo aws --version
sudo: aws: command not found

I'm here to address the change of aws command, see the discussion here.

If you need to execute aws command somewhere in your bootstrap script (or manual exection), please update your command to sudo /usr/local/bin/aws ... when you calling aws with sudo.
