on enter not working for TruffleRuby with the insight tool

[petenorth]

Describe GraalVM and your environment :

• GraalVM version or commit id if built from source: Nightly buld truffleruby 21.0.0-dev-5fd2b6b4, like ruby 2.7.2, GraalVM CE Native [x86_64-linux]
• CE or EE: CE
• JDK version: JDK8
• OS and OS Version: macOS
• Architecture: amd64

Have you verified this issue still happens when using the latest snapshot? Yes

Describe the issue The insight tool does not capture TruffleRuby method entries

Code snippet or code repository that reproduces the issue fibonacci.rb

def fib(n)
  first_num, second_num = [0, 1]
  (n - 1).times do
    first_num, second_num = second_num, first_num + second_num
  end
  puts first_num
end
fib(4)

and local-variable-trace.rb

puts("Ruby: Insight version " + insight[:version] + " is launching")

config = Truffle::Interop.hash_keys_as_members({
  roots: true
})

insight.on("enter", -> (ctx, frame) {
    puts(frame[:n].to_s)
}, config)

Steps to reproduce the issue ruby --insight=local-variable-trace.rb --experimental-options fibonacci.rb

Expected behavior In addition to the number 2 the frame strings should be printed for each method entry
