Synchronize Unicode license text from unicode.org

[dtolnay]

The text of https://unicode.org/license.txt was swapped out from "UNICODE, INC. LICENSE AGREEMENT - DATA FILES AND SOFTWARE" to "UNICODE LICENSE V3" between the dates of 2023.06.03 and 2023.09.11, which means between Unicode 15.0.0 (2022.09.13) and Unicode 15.1.0 (2023.09.12). A license wording change is not mentioned in the 15.1.0 release summary or announcement post. But I guess we are intended to infer that data files from Unicode 15.1.0 should be specified as licensed Unicode-3.0 as opposed to Unicode-DFS-2016.

The Rust standard library has been using Unicode 15.1.0+ since #120777.
