ROU-11327: Fix tooltip issue with Grouped Columns and increment version

[gnbm]

What was happening

• There was an issue where the column headers displayed incorrect tooltip content when using grouped columns in a Grid:

What was done

• Improved the validation about the tooltip method to be called on the internal event handler _onMouseEnter(e) because if the Column Header is from a Group Column, we need to use a different approach than the regular header.
• We can check if the current target is a ColumnGroup by checking its CSS class wj-colgroup and, if there is no binding and the number of columns inside ColumnGroup > 0 or if the number of columnGroups inside ColumnGroup > 0.

Test Steps

1. Go to a screen with two Grids, one with Grouped Columns and another without
2. On the one with Grouped Columns hover all Column Headers and check that the tooltip content is the expected
3. Repeat the same steps for the one without Grouped Columns for regression checks
