Comment (by jrf):

 @SergeyBiryukov I'd advocate for a different fix for [51633]: silencing
 the deprecation notice (for now).

 The actual `auto_detect_line_endings` functionality has not been removed
 from PHP (yet) and will still work until PHP 9.0 and while the old MacOS
 line ending of `\r` on its own, is nowadays a rarity to encounter, it may
 still exist in translation files which haven't been updated for a long
 time.

 Also see [https://github.com/squizlabs/PHP_CodeSniffer/pull/3394 this
 similar discussion elsewhere] about this.
