Update release notes to reflect `ScrollPosition` factory methods

[hantsy]

I followed the Spring Data release notes and try the new Scroll APIs, but found the methods mentioned in the doc used package scope.

I think these method should be public.

	/**
	 * Creates a new initial {@link OffsetScrollPosition} to start scrolling using offset/limit.
	 *
	 * @return will never be {@literal null}.
	 */
	static OffsetScrollPosition initial() {
		return INITIAL;
	}

	/**
	 * Creates a new {@link OffsetScrollPosition} from an {@code offset}.
	 *
	 * @param offset the non-negative offset to start at.
	 * @return will never be {@literal null}.
	 */
	static OffsetScrollPosition of(long offset) {
		return offset == 0 ? initial() : new OffsetScrollPosition(offset);
	}

This is a documentation issue. Please use ScrollPosition.offset() and ScrollPosition.keyset() factory methods. We just updated the docs.
