AskJSX documentation out-of-date

Current [AskJSX documentation](https://www.notion.so/AskJSX-JSX-dialect-for-AskScript-with-AskJSON-persistence-4df37b687888458ab63e1b9ee5037c3a) is out-of-date, which introduces errors during development.

Start with the linked AskJSX Notion documentation, then compare its examples and terminology with the current repository documentation or implementation. Done means the AskJSX documentation reflects the current project and no longer introduces development errors.
