custom-error-definition incompatible with instance class field + broken autofix

[fregante]

Two issues:

• the name instance class field isn't recognized
• the autofix does not carry the message and options like it should

export class BusinessError extends Error {
  name = "BusinessError";
}

After the autofix:

export class BusinessError extends Error {
	constructor() {
		super();
		this.name = 'BusinessError';
	}

	name = 'BusinessError';
}

See the before and after in the runtime, the message is lost:

Instance class fields have been supported since Node 12: https://node.green/#ES2022-features-instance-class-fields-public-instance-class-fields

So maybe the solution here would be to:

• Have the autofix produce name = "ErrorName" instead of creating a constructor

export class BusinessError extends Error {
+  name = "BusinessError";
}
