typo in split_cu_flag context derivation

Description

In 9.3.4.2.2 Derivation process of ctxInc using left and above syntax elements, the ctxSetIdx for split_cu_flag is derived as the following in table 9-83:
( allowSplitBtVer +

allowSplitBtHor +
allowSplitTtVer +
allowSplitTtHor +
2 * allowSplitQt − 1 ) / 3

This should be corrected as:
( allowSplitBtVer +

allowSplitBtHor +
allowSplitTtVer +
allowSplitTtHor +
2 * allowSplitQt − 1 ) / 2

The VTM software matches the corrected form, which is also aligned with the number of possible contexts for this syntax element.
