fix(useSession): add types for data property

[maou-shonen]

Referring to the example in #315

const session = await useSession<{ ctr: number }>(event, { password: sessionPassword });
await session.update((data) => ({ ctr: Number(data.ctr || 0) + 2 }));
session.data.ctr // type hints is any

However, getSession().data contains the correct hints, so this should be a bug.

I can confirm I noticed the same behaviour.

import { H3Event, useSession, SessionConfig } from "h3";

const sessionConfig: SessionConfig = {
  cookie: {
    // domain?: string
    // encode?: (value: string) => string;
    // expires?: Date
    httpOnly: true,
    // maxAge?: number
    path: "/",
    sameSite: "lax",
    secure: true,
  },
  // crypto?: Crypto;
  // maxAge?: number;
  name: "__auth",
  password: "s3cr3t",
  // seal?: SealOptions;
  // sessionHeader?: false | string;
};

export type AuthSession = {
  id: string;
  email: string;
};

export async function useAuthSession(event: H3Event) {
  const session = await useSession<AuthSession>(event, sessionConfig);
  console.log(session.data)
  //                   ^? data: SessionDataT [= Record<string, any>]
  return session;
}
