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'

Start by locating the InlineEditors docs sources, including the component readme.md and the ListBox/textarea story files. Check where the prop table, story names, and props are currently defined, then apply the requested updates: fix textarea props/story presence and rename the table story to "ListBox within a table." Run the project docs/storybook preview path used for component docs and verify the updated stories render cleanly with the missing textarea story present.
