ArgumentError message differs on multiple unknown keywords args

[deepj]

This is the same problem like in JRuby https://github.com/jruby/jruby/issues/4555

MRI returns all unknown kwargs while calling a method. Instead of TruffleRuby returns only first one.

To reproduce:

def foo(bar: 'baz'); end
foo(blah: nil, blah2: nil)

MRI (2.5.3):

Traceback (most recent call last):
        3: from ~/.rubies/ruby-2.5.3/bin/irb:11:in `<main>'
        2: from (irb):3
        1: from (irb):2:in `foo'
ArgumentError (unknown keywords: blah, blah2)

TruffleRuby (1.0.0.-rc10):

ArgumentError: unknown keyword: blah
    from (irb):2:in `foo'
    from (irb):3
    from ~/.rubies/truffleruby-1.0.0-rc10/bin/irb:29:in `<main>'

The problem is, TruffleRuby shows only the first invalid kwarg.

GraphQL specs seem to depend on this: https://github.com/rmosolgo/graphql-ruby/pull/726

Still a problem in truffleruby 22.2.0-dev-84832be1, like ruby 3.0.3, GraalVM CE Native [aarch64-darwin]
