Issue #3200 Add grant_notes and grant_notes_revisions table migration (…

…#3209)

* Create migration to add grant_notes and grant_notes_revisions tables

* Create migration to add grant_notes and grant_notes_revisions tables

* Add useConstraint modifier to the creation of the unique index.

Knex documentation says for the unique() function, that useConstraint will use a unique constraint and is default true for postgres when there is no predicate defined.
Issue #3200 specifies that we want a unique index.
Documentation can be found here: https://knexjs.org/guide/schema-builder.html#unique

* Lint
