Summary

We intend to change the Sec-CH-UA-Platform value from "Mac OS X" to "macOS"

Based on feedback we got from Apple, it seems useful to update the legacy "Mac OS X" platform name to the current "macOS" before we ship to 100% and further cement the legacy value.

Interoperability and Compatibility

Since we haven't yet launched this feature to 100%, and as we recently learned [1][2] that usage is *very, very* low, we feel like we can make this change now with minimal interop risks and pain to developers. Once we ship UA-CH to 100%, it's pretty much set in stone.

LGTM2, based on the same analysis we went through in the discussion around the client hint token names (https://groups.google.com/a/chromium.org/g/blink-dev/c/t-S9nnos9qU/m/pUFJb00jBAAJ).
