chore: fix aurora-mysql engine version (#5813)

Fixes #5812 

Currently used engine version `8.0.mysql_aurora.3.02.0` for aurora-mysql doesn't exists in AWS any more.

Based on the following script which grabs latest supported version of `aurora-mysql` in all regions - this should be changed to `8.0.mysql_aurora.3.06.0`:

```bash
❯ for REGION in `aws ec2 describe-regions --region us-east-1 --output text | cut -f4`; do
  echo "*** ${REGION}"
  aws rds describe-db-engine-versions --region "${REGION}" --engine aurora-mysql --query "DBEngineVersions[].EngineVersion" | sort | grep '8.0.mysql_aurora.3' | tail -1
done
*** ap-south-1
    "8.0.mysql_aurora.3.06.0"
*** eu-north-1
    "8.0.mysql_aurora.3.06.0"
*** eu-west-3
    "8.0.mysql_aurora.3.06.0"
*** eu-west-2
    "8.0.mysql_aurora.3.06.0"

    "8.0.mysql_aurora.3.06.0"

    "8.0.mysql_aurora.3.06.0"

*** us-west-1
    "8.0.mysql_aurora.3.06.0"
*** us-west-2
    "8.0.mysql_aurora.3.06.0"
```
