[Bug]: Generated name of enum type is incorrect when the attribute contains '[' or ']' characters

Package name

core

Package version

11.0.4

Reproduction steps

Create an API specification (json or yaml format) containing an endpoint with a parameter whose name contains '[' or ']' character.
Example:

{
	"openapi": "3.0.0",
	"info": {
		"version": "1.0",
		"title": "ApiManagement"
	},
	"paths": {
		"/api-management/api-definitions": {
			"get": {
				"tags": [
					"ApiDefinitions"
				],
				"summary": "Get REST and SOAP APIs",
				"description": "Get the list of REST and SOAP APIs that are available for my company",
				"operationId": "get-api-management-api-definitions",
				"parameters": [
					{
						"name": "filter[protocol]",
						"in": "query",
						"description": "Filter by ApiDefinition protocol",
						"allowEmptyValue": false,
						"schema": {
							"enum": [
								"REST",
								"SOAP",
								"1AXML"
							],
							"example": "REST"
						}
					}
				]
			}
		}
	}
}

Then generate the corresponding sdk.

nx g @ama-sdk/schematics:typescript-core --specPath ./swagger.yaml

Current result

The corresponding generated type does not compile:

/** Enum filter[protocol] used in the ApiDefinitionsApi's getApiManagementApiDefinitions function parameter */
export type ApiDefinitionsApiGetApiManagementApiDefinitionsFilter[protocol]Enum = 'REST' | 'SOAP' | '1AXML';

Expected result

I would expect a file that at least compile with something like

The corresponding generated type does not compile:

/** Enum filter[protocol] used in the ApiDefinitionsApi's getApiManagementApiDefinitions function parameter */
export type ApiDefinitionsApiGetApiManagementApiDefinitionsFilterProtocolEnum = 'REST' | 'SOAP' | '1AXML';

Additional comments

According to the Open API guide, it does not seem forbidden to use '[' or ']' special characters in the attribute name
