Incorrect 'Network interfaces per Region' limit

[jwu2]

Bug Report

Version

9.0.0

Installation Method

Docker

Supporting Software Versions

3.8.6

Actual Output

Currently the limit checker queries DescribeAccountAttributes API for "max-instances" attribute, then calculate with logic below:
This limit is the greater of either the default limit (350) or your On-Demand Instance limit multiplied by 5. The default limit for On-Demand Instances is 20.

Expected Output

According to https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeAccountAttributes.html, "max-instances" attribute is no longer supported.

Instead this limit is available in Service Quotas with Quota code L-DF5E4CA3 and the default value is 5000.

I have tested this check in the develop branch and can confirm it's working properly.
