return_unexpected_index_query returning broken query, escaping double quotes in result for SparkDFExecutionEngine

[jyoti-thakkar]

Describe the bug
we have set result_format as "COMPLETE" and return_unexpected_index_query to true, we want to use return_unexpected_index_query to get the error records from dataframe. It seems that it is returning broken query and escaping double quotes.
Example : return unexpected index query by GX : df.filter(F.expr(NOT(city IS NOT NULL)))
working query : df.filter(F.expr("NOT(city IS NOT NULL)"))

To Reproduce
import great_expectations as ge
from great_expectations.core import ExpectationSuite
from great_expectations.core.batch import RuntimeBatchRequest
from great_expectations.data_context import BaseDataContext
from great_expectations.data_context.types.base import FilesystemStoreBackendDefaults,DataContextConfig, DatasourceConfig

expectation_suite_config = {
"expectation_suite_name": "my_expectation_suite",
"expectations": [ # List of expectations
{
"expectation_type": "expect_column_values_to_not_be_null",
"kwargs": {
"column": "my_column",
"result_format": {"result_format": "COMPLETE"}

        }
    }
]

}

my_expectation_suite = ExpectationSuite(**expectation_suite_config)

Define DataContext configuration

data_context_config = DataContextConfig(
plugins_directory=None,
config_variables_file_path= None,
datasources={
"my_spark_datasource": DatasourceConfig(
class_name= "Datasource",
execution_engine={
"class_name": "SparkDFExecutionEngine",
"force_reuse_spark_context": True,

        },
        data_connectors={
            "spark_runtime_dataconnector":{
                "class_name": "RuntimeDataConnector",
                "module_name":"great_expectations.datasource.data_connector",
                "batch_identifiers": ["batch_name"]
            },
        },
    )
},
store_backend_defaults=FilesystemStoreBackendDefaults(root_directory="/"),

)

batch_request=RuntimeBatchRequest(datasource_name="my_spark_datasource",
data_connector_name="spark_runtime_dataconnector",
data_asset_name="my_asset",
runtime_parameters={"batch_data": df},
batch_identifiers={"batch_name": "batch_run"})

context = ge.get_context(project_config=data_context_config)
batch_validator = context.get_validator(batch_request=batch_request, expectation_suite=my_expectation_suite)
validation_result = batch_validator.validate()
print(validation_result)

validation_result contains unexpected_index_query value as "df.filter(F.expr(NOT(city IS NOT NULL)))"

when i execute this query it is giving error syntax error. Invalid syntax

Expected behavior
Executing Query should result into getting error records from dataframe

Environment (please complete the following information):

• Operating System: [e.g. Linux, MacOS, Windows] --> Windows
• Great Expectations Version: [e.g. 0.13.2] --> 0.18.13
• Data Source: [e.g. Pandas, Snowflake] --> spark dataframe
• Cloud environment: [e.g. Airflow, AWS, Azure, Databricks, GCP] --> Databricks
