Custom Classifiers for AWS Glue to able to change the variable datatypes

### Name of the resource

AWS::Glue::Classifier

### Resource name

AWS::Glue::Classifier CsvClassifier

### Description

The CSVClassifiers CustomDatatypes property is not available in the CSV-Classifiers property of the cloud formation, but I can see it in the console. Please add CustomDatatype properties in AWS: Glue::Classifier CsvClassifier. to the AWS CloudFormation template.

Custom Datatypes as an Example for the Console
Reference: https://docs.aws.amazon.com/glue/latest/dg/custom-classifier.html#custom-classifier-csv --> This link says what is there in the console.

### Other Details

Reference: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-glue-classifier-csvclassifier.html

Reference :https://docs.aws.amazon.com/glue/latest/dg/custom-classifier.html#custom-classifier-csv -> This link says what is there in console

Start by comparing the AWS CloudFormation CSVClassifier reference with the AWS Glue custom classifier documentation linked in the issue. Confirm the missing CustomDatatypes properties and trace how AWS::Glue::Classifier coverage is represented in this repository. Done means the CsvClassifier schema supports the documented custom datatype properties.
