InlineEditors documentation problems

The docs of the new InlineEditors components need some work:

- [x] there should be a standard readme.md file with the prop table
- [ ] ~do we need these interactive examples in the docs, plus stories? it's twice the maintenance~
- [ ] ~in the ListBox example, rename 'someOptions' to 'subscriptions'~
- [ ] ~the 'textarea' example is broken (clicking it, screen goes white)~
- [x] the 'textarea' example has the wrong props
- [x] there's no 'textarea' story
- [x] rename 'with in a table' story to 'ListBox within a table'

首先定位 InlineEditors 的文件來源，包括 component readme.md 以及 ListBox/textarea story 檔案。檢查 prop 表格、story 名稱和 props 目前定義的位置，然後套用要求的更新：修正 textarea props/story 的存在性，並將表格 story 重新命名為 "ListBox within a table."。執行用於元件文件的專案 docs/storybook 預覽路徑，並確認更新後的 stories 能正常呈現，且缺少的 textarea story 已存在。
