Update glossary in Traditional Chinese (zh-TW)'s i18n guide

[vrabe]

It's been almost 2 years since the latest glossary change (#7559). Astro docs changed a lot during these times. In the last months, @lumynou5 made efforts trying to revise the glossary. (#12666, #12667, #12693) I think it's a great time to take a look on the glossary and add more terms on it. And #12693 seems not going to be reopened. So I create this discussion to gather opinions.

@lumynou5 and I have discussed about this in #12693:

• repository
  • @lumynou5 suggested 儲存庫 -> 版本庫
• on-demand render
  • I suggested 隨需算繪
  • @lumynou5 thought 算繪 is not good
• page partial
  • @lumynou5 suggested 缺略頁面 or 非完整頁面
  • I thought 非完整頁面 is better
• schema
  • I suggested 資料標準
  • @lumynou5 thought (資料)結構描述 is more descriptive

If my conclusion is wrong or missing something, please correct me.

Any suggestions are welcome.
