SQS queue does not have Server Side Encryption enabled

[rjlupinek]

The SQS queue used in this project does not have Encryption Enabled. This was reported when we ran Prowler against a development environment where this was deployed. This is not part of CIS, but we were hoping this could be resolved at some point.

Findings output:
