Documentation Edit: Curly Apostrophes

In 9.1.6 Multiple syllables to one note
<https://lilypond.org/doc/v2.27/Documentation/notation/common-notation-for-=
vocal-music#multiple-syllables-to-one-note>,
the apostrophes within lyrics should be curly (=E2=80=99) instead of straig=
ht (').

Here is a revised example:


{
  \relative {
    \autoBeamOff
    r8 b' c fis, fis c' b e,
  }
  \addlyrics
  {
    % Ensure hyphens are visible
    \override LyricHyphen.minimum-distance =3D 1.0
    Che_in ques -- ta_e_in quel -- *l=E2=80=99al* -- *tr=E2=80=99on* -- da
  }
  \addlyrics { "Che in" ques -- "ta e in" quel -- *l=E2=80=99al* -- *tr=E2=
=80=99on* -- da }
  \addlyrics { Che~in ques -- ta~e~in quel -- *l=E2=80=99al* -- *tr=E2=80=
=99on* -- da }
}
