Update DB docs to add text limit in one migration
What does this MR do and why?
Updates the database documentation for adding text column to existing tables.
We advise adding text limits in a separate migration, even though there is a cop that must be disabled. This MR adds more explanation about this and advices to add the text limit in the same migration but check if the column already exists.
