Version 5.1.0

Other changes

• Fix comma_formats resolution so a superclass's comma block reopened after a subclass is defined (including ActiveRecord STI subclasses) is picked up instead of using a stale snapshot.
• Raise Comma::CircularStyleReference instead of a stack overflow when named styles reference each other cyclically via __use__.
• Add support for Rails 8.0 and 8.1; update the tested Rails matrix to 7.1.6, 7.2.3.2, 8.0.5.1, and 8.1.3.1.
• Document how to export dynamic, per-instance CSV columns and renamed headers.
