str.join: Append `str`ed element to error message

The Starlark error message for `str.join` used to be:
expected string for sequence element %d, got '%s'
; with the index of the erroneous element and its `type`

Now it is:
expected string for sequence element %d, got '%s' of type %s
; which adds and emphasizes the `str` value of the element
to the prior error message for aid in disambiguation
