feat(session): implement the data loader of sessions

[pan93412]

Port the script at https://github.com/COSCUP/2024/blob/eff079441b85a3007a357c071ff1df243bf80738/scripts/pre-build/generateSession.ts as a VitePress data loader. Ensure proper typing according to the Pretalx API documentation and reorganize the code structure.

Usage:

import { data } from '#loaders/session.data'

Please note that we fetch the sessions from COSCUP 2024, as the sessions for 2025 have not been released yet.

You can optionally pass a PRETALX_TOKEN to access restricted resources, although the sessions for COSCUP 2024 are open.

You can check the generated result in #34.

Squashed from commit 4312f65

TODOs:

• 把 session / speaker / room 分成幾個 data loaders 來用
• 實驗出比較適合前端呈現的格式 (experiment in Add a simple prototype of session time  #34)

我記得 dataloader 不會主動讀 .env。你可以驗證一下他會不會把你指定的 PRETALX_TOKEN 讀進去。
