ep: Fix incorrect example count in failure summary (#46257)

The 'X of Y examples failed' message was counting completed steps/tasks
instead of actual examples. For example, with 2 examples each going
through Load and Context steps, it would report '1 of 3' instead of '1
of 2'.

Release Notes:

- N/A
