Update a post

Uses the create post endpoint to update the original post.

Update the specific post by creating a new post with the post_type amend and the original post item_hash as the ref along with the new content.

Example

>>> from aleph_client.synchronous import create_post

>>> create_post(
      account, 
      {'content': 'test'}, 
      post_type='amend', 
      ref="<ITEM HASH HERE>",
      channel='MY_CHANNEL')
