error with ruby 3.3.1: names.rb:51:in `to_s': wrong number of arguments #168

I'm running bibtex-ruby via jekyll-scholar via jekyll. After upgrading to ruby 3.3.1 (on Fedora 40), I get the following hard errors when rebuiling a website:

/usr/share/gems/gems/bibtex-ruby-6.0.0/lib/bibtex/names.rb:105:in `block (3 levels) in <class:Names>': undefined method `convert!' for an instance of String (NoMethodError)

    from /usr/bin/jekyll:25:in `load'
    from /usr/bin/jekyll:25:in `<main>'

I tried to fix that by changing n.to_s(options) to n.to_s (although I see that to_s is defined for the class on the very next line, so I'm not sure why it's failing.

However, I then get:

/usr/share/gems/gems/bibtex-ruby-6.0.0/lib/bibtex/names.rb:105:in `block (3 levels) in <class:Names>': undefined method `convert!' for an instance of String (NoMethodError)

        tokens.each { |t| t.send(method_id, *arguments) }

    from /usr/share/gems/gems/bibtex-ruby-6.0.0/lib/bibtex/value.rb:271:in `convert'

at which point I opened this ticket. It works fine on Fedora 39 with Ruby-3.2.4, so maybe there were incompatible changes in ruby?

(I also looked at the code for bibtex-ruby-6.1 and it didn't change these parts of names.rb.)

Suggestions? Do you need a test case, or is "try ruby-3.3" sufficient?

I believe version 6.1 fixes this (here's the relevant change)

Yes, thank you very much! Sorry to be not up-to-date.
