Inspector Report requires aws configure tweak to run on cli v2

[gdelisle]

I just ran into this migrating the ct-patching-scanning Jenkins jobs from a host where awscli v1 was installed to a host where awscli v2 is installed. Running the Inspector Report gave me this console error:
date: invalid date ‘@2024-07-08T12:08:26.315000-04:00’

This isn't a problem with the date command, but a breaking change in date format output between aws cli v1 and v2:
https://docs.aws.amazon.com/cli/latest/userguide/cliv2-migration-changes.html#cliv2-migration-timestamp
By default, all dates returned to the cli are reformatted into ISO 8601 format. The fix is to configure your aws cli tool with cli_timestamp_format = wire and there is no environment variable or command line option to do this. I can confirm that this config file option fixed the script for me without the need to change any code.

If a fix is desired, it could be along the lines of conditionally removing the prefixed @ from the date input; while this gives an error:
date --date='@2024-07-08T11:00:02.414000-04:00'
this works fine:
date --date='2024-07-08T11:00:02.414000-04:00'
That might be desired for the long term, since the "wire" option only refrains from reformatting the date stamp that's delivered from the inspector service. If a future update to the inspector service outputs the date in ISO 8601 format, the config file option won't fix the format.
