TColumn.sort Has Wrong Definition

[dday9]

The documentation states that a TColumn's sort property's type can either be a Boolean or a SortConfig: https://gridjs.io/docs/config/sort#generic-sort-config

However, the TColumn interface defines the sort property as a nullable SortConfig: https://github.com/grid-js/gridjs/blob/master/src/types.ts#L34

The code behaves like the documentation, so the interface should be updated to reflect the documentation:

export interface TColumn {
  // ...
  sort?: boolean | SortConfig;
  // ...
}
