ParseError: 107 'false' is not a valid value for class level permissions delete:*:false

New Issue Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest version of Parse Server.

Issue Description

I can't set CLP for delete to false. I want to do this so that only the master can delete objects. It is unclear from the documentation why this would not work.
The same error occurs for update and create!

Steps to reproduce

const TestSchema = 
{
	className: "Test123",
	classLevelPermissions: {
		delete: {
			'*': false
		}
	},

	fields: 
	{
		"objectId": {
			"type": "String"
		},
		"createdAt": {
			"type": "Date"
		},
		"updatedAt": {
			"type": "Date"
		},
		"ACL": {
			"type": "ACL"
		},
		"name": {
			"type": "String",
			"required": true
		},
	}
}

Create a server with following options:

  schema: {
    definitions: [
      TestSchema,
    ]
  },

Actual Outcome

error: Failed to run migrations: 
Error while saving Schema for type Test123: 
ParseError: 107 'false' is not a valid value for class level permissions delete:*:false

Expected Outcome

It should work?

Environment

Logs

Start by reproducing the schema migration with the classLevelPermissions delete, update, and create settings shown in the issue. Trace how Parse Server validates and saves these permissions, then add or update coverage for false values and confirm that restricting these operations to master-only works without a migration error.
