chore[migrations]: added migration for note data

[e11sy]

Problem

We recently added tools field for public.note table, and now tools are inserted on appropriate routes
See #251 for more information
But old notes that were in table before tools field implementation are now having null in tools

Solution

Added migration that checks for note tools inside content.blocks of each note and adds appropriate array into tools field
