String freeze exception for Krita 5.2 branch

[Drawpile]

Hello translators,

there's some new strings added to Krita's 5.2 branch relating to touch-and-hold color picking. It solves some usability and accessibility issues for users that could not see or operate the color picker before.

The changes pertain to a setting where to place the color picker preview and to configure its size, required for different handedness and device sizes. See https://invent.kde.org/graphics/krita/-/merge_requests/2534/diffs
