## Why this Approach

- our current version of tiptap is 3.4.2 while the latest is 3.8.0 hence
installing these versions manually would install the latest version of
3.8.0. The issue when downgrading to 3.4.2 was that Version 3.8.0 of
`@tiptap/extension-list` requires `renderNestedMarkdownContent` from
@tiptap/core
but our `@tiptap/core` version 3.4.2 doesn't export this function.
