Fetchers not accepting return type param

[carboni-rob]

Type: bug
Versions: openapi-codegen/cli: 2.0.0, openapi-codegen/typescript: 6.1.0
Description: generated fetchers do not accept a return type parameter. As a result, the fetcher return type is Promise<undefined>.
Example:

export const fetchExportLogs = (
  variables: ExportLogsVariables,
  signal?: AbortSignal
) =>
  apiFetch<
    undefined,
    ExportLogsError,
    undefined,
    {},
    ExportLogsQueryParams,
    ExportLogsPathParams
  >({
    url: '/audit-logs/export',
    method: 'get',
    ...variables,
    signal,
  });

Results in

Expected result:

export const fetchExportLogs = <TData>(
  variables: ExportLogsVariables,
  signal?: AbortSignal
) =>
  apiFetch<
    TData,
    ExportLogsError,
    undefined,
    {},
    ExportLogsQueryParams,
    ExportLogsPathParams
  >({
    url: '/audit-logs/export',
    method: 'get',
    ...variables,
    signal,
  });
