Make `prefer_line` the default soft-wrap behavior. (#11542)

Stops lines from clipping at 1024 by default, returning it to the old
default behaviour where it wraps at 512. The `none` mode is only
supposed to be used for git hunks. See
https://github.com/zed-industries/zed/issues/11518#issuecomment-2099836283.
