🔨: remove unused `jobLoading` ref in `DatasetDetails`

const { currentUser } = storeToRefs(userStore);

const loading = ref(false);

const jobLoading = ref(true);

const jobTimeOut = ref<any>(null);

const jobDetails = ref<JobDetails>();

const dataset = ref<HDADetailed | null>(null);

}

async function loadJobDetails() {

    jobLoading.value = true;

    try {

        const { data } = await fetchJobDetails({ job_id: dataset.value?.creating_job as string, full: true });

        const error = e as AxiosError<{ err_msg?: string }>;

        jobLoadingError.value = error.response?.data?.err_msg || "Unable to fetch available dataset details.";

    } finally {

        jobLoading.value = false;

    }
