Examples: JSON Tree broken

[lovetox]

Hi,

the json_tree.py example seems broken with 0.10.1

i get an import error

Traceback (most recent call last):
  File "/home/lovetox/projects/testtextualapp/textual/examples/json_tree.py", line 8, in <module>
    from textual.widgets.tree import TreeNode
ModuleNotFoundError: No module named 'textual.widgets.tree'

Where did you get the jason_tree.py example from? By the looks of things you're attempting to use the code from the main branch of Textual, with the library as of v0.10.1. The way that TreeNode is imported has changed so mixing and matching that code won't work. If you want to use the examples that work with v0.10.1 it's best to download either download the source for that release, or use the example from the v0.10.1 tag.
