Use a range of years for copyright in LICENSE

[Stevoisiak]

Documentation

Most copyright notices in cpython use a range of years.

cpython/Doc/license.rst

Lines 103 to 105 in 616aec1

	copyright, i.e., "Copyright © 2001-2023 Python Software Foundation; All Rights
	Reserved" are retained in Python |release| alone or in any derivative version
	prepared by Licensee.

The LICENSE file is an exception.

cpython/LICENSE

Lines 86 to 89 in 616aec1

	i.e., "Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010,
	2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 Python Software Foundation;
	All Rights Reserved" are retained in Python alone or in any derivative version
	prepared by Licensee.

Similar to how the README was simplified in #10287, the LICENSE should use a range of years for readability and consistency.

Fixed in #113608, thanks for the report and the initial PR!

FWIW, updating copyright years every year does not make sense and is IMHO useless churn that has zero legal value and has zero technical value.
