### Current Behavior

This looks similar to https://github.com/localstack/localstack/issues/6471

I am trying to sign something using KMS for some tests. It seems like doing so using an alias does not work. For example I create a key and an alias like so:

```
# Add a key used for signing urls
aws-cli --endpoint-url=http://localhost:4566 kms create-key \
  --key-usage SIGN_VERIFY \
  --key-spec RSA_4096 


# Add well known alias for key
aws-cli --endpoint-url=http://localhost:4566 kms create-alias \
  --alias-name "some-nice-alias-name" \
  --target-key-id <key id generated above>
```

I can see that this looks to have worked by verifying the key and alias on the CLI

```
aws-cli --endpoint-url=http://localhost:4566 kms list-keys
{
    "Keys": [
        {
            "KeyId": "f7d2d869-f6b8-4977-96ea-5bd70cb0d5f2",
            "KeyArn": "arn:aws:kms:us-east-1:000000000000:key/<someuuid>"
        }
    ]
}
```

and

```
 aws-cli --endpoint-url=http://localhost:4566 kms list-aliases
{
    "Aliases": [
        {
            "AliasName": "census-webform-url-signing-key",
            "AliasArn": "arn:aws:kms:us-east-1:000000000000:alias/some-nice-alias-name",
            "TargetKeyId": "<sameuuid>",
            "CreationDate": "2023-01-13T16:58:52.279782-05:00"
        }
    ]
}
```

however attempting to sign something does not work

```
# Make sure we can sign
aws-cli --endpoint-url=http://localhost:4566 kms sign \
  --cli-binary-format raw-in-base64-out \
  --key-id "alias/some-nice-alias-name" \
  --message 'wwwtestcom' \
  --message-type RAW \
  --signing-algorithm "RSASSA_PSS_SHA_512"
 
```
  
results in 

An error occurred (NotFoundException) when calling the Sign operation: Unable to find KMS alias with name alias/some-nice-alias-name


### Expected Behavior

Would expect output from the last command not the resulting 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`)

    docker run localstack/localstack

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

```
aws-cli --endpoint-url=http://localhost:4566 kms create-key \
  --key-usage SIGN_VERIFY \
  --key-spec RSA_4096 


aws-cli --endpoint-url=http://localhost:4566 kms create-alias \
  --alias-name "some-nice-alias-name" \
  --target-key-id <key id generated above>

aws-cli --endpoint-url=http://localhost:4566 kms list-keys
{
    "Keys": [
        {
            "KeyId": "f7d2d869-f6b8-4977-96ea-5bd70cb0d5f2",
            "KeyArn": "arn:aws:kms:us-east-1:000000000000:key/<someuuid>"
        }
    ]
}

 aws-cli --endpoint-url=http://localhost:4566 kms list-aliases
{
    "Aliases": [
        {
            "AliasName": "census-webform-url-signing-key",
            "AliasArn": "arn:aws:kms:us-east-1:000000000000:alias/some-nice-alias-name",
            "TargetKeyId": "<sameuuid>",
            "CreationDate": "2023-01-13T16:58:52.279782-05:00"
        }
    ]
}

aws-cli --endpoint-url=http://localhost:4566 kms sign \
  --cli-binary-format raw-in-base64-out \
  --key-id "alias/some-nice-alias-name" \
  --message 'wwwtestcom' \
  --message-type RAW \
  --signing-algorithm "RSASSA_PSS_SHA_512"
```


### Environment

```markdown
- OS: Macos 12.6.2
- LocalStack: latest docker image
```


### Anything else?

I did test using the same using the actual generated key ID and this works. I also attempted this through a BOTO3 client in python and the same resulted.
