PaginateConfig has string default type for some attributes even it's a generic interface

[sitoftonic]

While using the PaginateConfig interface, when trying to provide values to filterableColumns or select attributes, I cannot get hints about real attributes in the entity, even that PaginateConfig has a required generic type.

For example, having this:

const config: PaginateConfig<MeetingEntity> = {
  filterableColumns: {
    name: true,
    // Cursor placed here
  },
};

And placed just below the name: true, when pressing CTRL+I in VSCode to get hints about other attributes in MeetingEntity, I cannot get the attributes. The definition of PaginateConfig is as follows:

export interface PaginateConfig<T> {
  relations?: FindOptionsRelations<T> | RelationColumn<T>[] | FindOptionsRelationByString
  sortableColumns: Column<T>[]
  nullSort?: 'first' | 'last'
  searchableColumns?: Column<T>[]
  select?: Column<T>[] | string[]
  maxLimit?: number
  defaultSortBy?: SortBy<T>
  defaultLimit?: number
  where?: FindOptionsWhere<T> | FindOptionsWhere<T>[]
  filterableColumns?: {
      [key in Column<T> | string]?: (FilterOperator | FilterSuffix)[] | true
  }
  loadEagerRelations?: boolean
  withDeleted?: boolean
  paginationType?: PaginationType
  relativePath?: boolean
  origin?: string
  ignoreSearchByInQueryParam?: boolean
  ignoreSelectInQueryParam?: boolean
}

To solve the problem, the | string in both attributes should be removed, as there is no valid way PaginateConfig does not have a type provided and defaulting to string breaks previous Column<T> typing. This also bypasses static analysis for non existing attributes.

I have tried to create a PR with these changes but I'm not allowed to push to the repository.
