Fix #29451 - No dots in TAB styles which use them

In a TAB with the "Stem through staff" style, augmentation dots are not shown.

Fixed, by invoking the function which creates dots for standard staff (`setDotY()`); this function is in a work-flow which is not executed for TAB's (as a number of layout steps, like those for accidentals, are not needed for TAB's).
