[Enhancement] Document usage of element0/element1 in addition to usage of elementIndex0/elementIndex0 in nestedforEach

[iamsgarg-ob]

Description

The current documentation in nested foreach talks about

• element - current element in the innermost loop in nested foreach
• elementIndex - index of the element of the outer loop ( elementIndex0 ) and the inner loop ( elementIndex1 ) and so on..

however it does not reference that you can refer to the outer loop element as {{ element0 }} or that the inner loop element can be referenced as {{ element1 }} and so on.

It would be very helpful to document this so users of nested foreach's dont have to rely on anti patterns like assigning the outer loop element to some context variable and then referencing it in the inner loop.
