BREAKING CHANGE: In pagination `forward` was renamed to `direction`.

BREAKING CHANGE: To paginate backward use `'backward'` in `pagination.direction` instead of `false` in `pagination.forward`. Use `import { backward } from '@js-entity-repos/core/dist/types/PaginationDirection'`.
BREAKING CHANGE: To sort in ascending order use `'asc'` in `sort` instead of `true`. Use `import { asc } from '@js-entity-repos/core/dist/types/SortOrder'`.
BREAKING CHANGE: To sort in descending order use `'desc'` in `sort` instead of `false`. Use `import { desc } from '@js-entity-repos/core/dist/types/SortOrder'`.
