typescript root enum requests still failing to build

[baywet]

follow up to #4199

beta build gets the following error Error: deviceManagement/chromeOSOnboardingSettings/connect/index.ts(89,9): error TS2322: Type 'string' is not assignable to type 'Record<string, unknown>'.

This matches the "enumObject" part of this section

export const ConnectRequestBuilderRequestsMetadata: RequestsMetadata = {
    post: {
        uriTemplate: ConnectRequestBuilderUriTemplate,
        responseBodyContentType: "application/json",
        errorMappings: {
            XXX: createODataErrorFromDiscriminatorValue as ParsableFactory<Parsable>,
        },
        adapterMethodName: "sendEnum",
        enumObject: "ChromeOSOnboardingStatus",
        requestBodyContentType: "application/json",
        requestBodySerializer: serializeConnectPostRequestBody,
        requestInformationContentSetMethod: "setContentFromParsable",
    },
};

I believe the generation should not emit the quotes around ChromeOSOnboardingStatus, but it remains to be investigated
