Documentation mentions private `ScrollPosition` factory methods

[1pinus]

Documentation 4.4.4 says to use.
OffsetScrollPosition.initial()
but compiler complains that initial() is not public. I couldn't figure out how to use it.

Apologies for inconvenience. Use ScrollPosition.offset() for an initial offset scroll position and ScrollPosition.keyset() for an initial keyset scroll position. We have to fix our docs.

Docs are updated now.
