### Expected Behavior

Generated a file inst.pem without error.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)
version: '3.2'

networks:
  netapp:

services:
  localstack:
    image: localstack/localstack:1.2
    environment:
      AWS_ENDPOINT: "http://localstack:4566"
      SERVICES: lambda,apigateway,iam,s3,dynamodb,sts,cloudwatch,events,kms,ssm,kinesis,logs,sns,sqs,secretsmanager
      LAMBDA_EXECUTOR: docker
      DOCKER_HOST: unix:///var/run/docker.sock
      LAMBDA_CONTAINER_REGISTRY: "lambci/lambda"
      LAMBDA_REMOTE_DOCKER: "true"
      LAMBDA_DOCKER_NETWORK: netapp
      HOSTNAME_EXTERNAL: localstack
      EDGE_PORT: 4566
      DEBUG: 1
    ports:
      - 4566:4566
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

1. Run ```AWS_REGION=eu-west-3 AWS_ACCESS_KEY_ID=fake AWS_SECRET_ACCESS_KEY=fake aws --endpoint-url="http://localhost:4566" kms create-key --customer-master-key-spec="RSA_2048" --key-usage="SIGN_VERIFY" --description="test1839"```
2. Take the value of "KeyMetadata.KeyId"
3. Run ```AWS_REGION=eu-west-3 AWS_ACCESS_KEY_ID=fake AWS_SECRET_ACCESS_KEY=fake aws --endpoint-url="http://localhost:4566" kms get-public-key --key-id [keyid] --output text --query PublicKey | base64 -d > inst.der```
4. Run ```openssl rsa -pubin -inform DER -outform PEM -in inst.der -pubout -out inst.pem```

Then you obtains this result


I followed these steps "https://aws.amazon.com/fr/blogs/security/how-to-verify-aws-kms-asymmetric-key-signatures-locally-with-openssl/".

I have the version 1.2.0 of localstack, arch arm64.


### Environment

```markdown
- OS: macOs Montery 12.6.1 (MacBook Air (M1, 2020)
- Chip: Apple M1
- Memory: 16 GB
- LocalStack: 1.2.0
```


### Anything else?

It works with the current original AWS.

We started to investigate when the error "x509: malformed tbs certificate" appers in our logs from our application in go.
