Make the Lezer parser for Heynote documents use overlay parsers for the individual blocks

Browse Source 
This fixes the issue with some blocks not being foldable (since the NoteContent nodes were getting replaced by the tree produced by the sub-parser).

Update the todo-checkbox plugin to use regular expression to find the todo list syntax, since it was previously relying on the parsed syntax tree, and the markdown syntax tree is no longer available in the main document's syntax tree.
