Using multiple starred targets on the left side of `=` gets the error message saying "starred expressions" instead of "starred targets"

Bug report

Bug description:

The doc says starred target as shown below:

*Memo:

• The doc also says star_target.

If the target list contains one target prefixed with an asterisk, called a “starred” target:

But using multiple starred targets on the left side of = gets the error message saying starred expressions instead of starred targets as shown below:

*v1, *v2, *v3 = [0, 1, 2, 3, 4]
# Error

SyntaxError: multiple starred expressions in assignment

So, the error message should say starred targets as shown below:

SyntaxError: multiple starred targets in assignment

And, using a single starred target on the left side of = gets the error message saying starred assignment target as shown below:

*v = [0, 1, 2, 3, 4]

SyntaxError: starred assignment target must be in a list or tuple

So, the error message should say starred target as shown below:

SyntaxError: starred target must be in a list or tuple in assignment
