Inconsistent behavior of SageMaker Client Search Method for Model Packages

Environment Information

Python Version: 3.10.14 boto3 == 1.24.4 pytest == 8.3.2 moto == 5.0.13

Problem Description

I believe this issue is very similar to #7898. I'm also using moto to test the retrieval of models, this time model packages instead of model package groups. I've created some model packages using create_model_package and when using the Resource ModelPackage in sagemaker_client.search, no model packages were returned. On the other hand, I had results returned when using the Resource ModelPackageGroup.

I also tried to list_model_packages with the same set of created model packages and had two outcomes:

When using ModelPackageGroupName: the models that were under the provided model package group were returned.
When not using any parameters: an empty list was returned.

Minimal Example

search_model_package.py

import boto3

class ModelPackageFinder:
    def __init__(self):
        self.sm_client = boto3.client('sagemaker')

    def get_model_groups_with_search_method(self):
        search_results = self.sm_client.search(
            Resource='ModelPackage',
            SearchExpression={
                'Filters': [{
                    'Name': 'ModelPackageName', 
                    'Operator': 'Contains', 
                    'Value': 'model-test'}]}
        )
        return search_results

    def get_model_packages_with_list_model_packages_method(self):
        list_model_results = self.sm_client.list_model_packages()
        return list_model_results

    def get_model_packages_with_list_model_packages_method_and_group(self):
        list_model_results = self.sm_client.list_model_packages(ModelPackageGroupName="model-test_DEV")
        return list_model_results

As seen above, the sm_client.search did not return any results when using the ModelPackage Resource. The sm_client.list_model_packages method also did not return anything when passing no parameters, but it did when passing the ModelPackageGroupName parameter.
