docs(sdk): document remaining AWS checks gated by --scan-unused-services

- Add missing checks under ACM, Athena, EC2 and VPC sections
- Add Bedrock, KMS and RDS sections covering checks gated by the flag
- Correct EC2 security group count from 15 to 20
- Fix "encyption" typo in the EC2 EBS paragraph
