Ignore tags with prefix aws: instead of aws

[tamimkh]

Description

In the AWS documentation, the aws: prefix is called out as being reserved for internal AWS use. However, in this resource we filter out all tags that start with aws instead of the more specific aws:.

This PR attempts to correct this by filtering out any tags that start with aws: instead of the more general aws.
