Remove duplicated text for iterable unpacking

[jiasli]

This text is duplicated several lines later in L139-L141:

cpython/Doc/reference/simple_stmts.rst

Lines 139 to 141 in c56f9df

	* Else: The object must be an iterable with the same number of items as there
	are targets in the target list, and the items are assigned, from left to
	right, to the corresponding targets.

Putting it after the first Else: causes confusion.

I don't think the else and indentation really improves the readability of the text here as it is implied by it being an another condition. For example something like this would suffice in my opinion

Assignment of an object to a target list, optionally enclosed in parentheses or
square brackets, is recursively defined as follows.

* If the target list is a single target with no trailing comma,
  optionally in parentheses, the object is assigned to that target.

* If the target list contains one target prefixed with an asterisk, called a
  "starred" target: <...>

* Otherwise the object must be an iterable with the same number of items as there
  are targets in the target list, and the items are assigned, from left to
  right, to the corresponding targets.

@Numerlor, I agree, but I only want to eliminate duplication in this PR as it is obviously wrong. As for the content itself, I will leave it to the python maintainer.
