master 1850121629 2/2: Avoid deprecation warning in NS-specific code

[Mattias Engdegård]

branch: master
commit 1850121629d19515130225232bbc020a168aee2e
Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Avoid deprecation warning in NS-specific code
    
    * src/macfont.m (mac_font_create_preferred_family_for_attributes):
    CTGetCoreTextVersion is obsolete and its use elicits a warning
    in macOS 11.6; use NSProcessInfo instead.
