Checks correct naming for named fresh middleware export.
Files inside the routes/ folder can export middlewares that run before any
rendering happens. They are expected to be available as a named export called
handler. This rule checks for when the export was incorrectly named handlers
instead of handler.
Invalid:
export const handlers = {
  GET() {},
  POST() {},
};
export function handlers() {}
export async function handlers() {}
Valid:
export const handler = {
