Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When calling AWS eventbridge PutEvents with LocalStack, a PutEventsRequestEntry array with more than 10 entries can go through successfully with a resulting FailedEntryCount of zero.

Expected Behavior

When calling AWS eventbridge PutEvents with LocalStack, a PutEventsRequestEntry array with more than 10 entries should return an error on the entire request.

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 events put-events \
 --region us-east-1 \
 --endpoint-url http://localhost:4566 \
 --entries '[{"DetailType": "Test", "Detail": "{\"test1\": \"test1\"}", "Source": "testing.123"},
 {"DetailType": "Test", "Detail": "{\"test2\": \"test2\"}", "Source": "testing.123"},
 {"DetailType": "Test", "Detail": "{\"test3\": \"test3\"}", "Source": "testing.123"},
 {"DetailType": "Test", "Detail": "{\"test4\": \"test4\"}", "Source": "testing.123"},

 {"DetailType": "Test", "Detail": "{\"test12\": \"test12\"}", "Source": "testing.123"}]'
