Fix more test failures; remove Array#to_proc

- Remove Array#to_proc (from PR#233) — interferes with assertion
  library by making all arrays implicitly convertible to procs
- Fix Hash#rekey and Hash#revalue arity check for Symbol#to_proc
  (arity is -2 in Ruby 3.4, not -1; use == 2 check instead)
- Remove stale dup!/try_dup tests
- Update changelog

Test results: 1257 tests, 1223 passing, 15 errors, 5 failures, 14 pending
