StringIO.set_encoding_by_bom()

[rurounijones]

Some of our code makes use of this method: https://ruby-doc.org/3.2.2/exts/stringio/StringIO.html#method-i-set_encoding_by_bom

This fails in our test suite when running TruffleRuby 24.0.2

     NoMethodError:
       undefined method `set_encoding_by_bom' for #<StringIO:0x848638>

This does not appear to be implemented in Truffleruby butset_encoding is :

truffleruby/lib/truffle/stringio.rb

Line 203 in 3cd4224

def set_encoding(external, internal = nil, options = nil)

(As a sidenote: Love what you guys are doing with TruffleRuby; excited for the future)
