This is because `join` wants the operator to come before the location

This is an experimental implementation for
https://bugs.ruby-lang.org/issues/21543.

```
test.rb:2:in 'Object#foo': wrong number of arguments (given 1, expected 2) (ArgumentError)

    caller: test.rb:6
    |   foo(1)
        ^^^
    callee: test.rb:2
    | def foo(x, y)
          ^^^
        from test.rb:6:in 'Object#bar'
        from test.rb:10:in 'Object#baz'
        from test.rb:13:in '<main>'
```

Fixes https://github.com/ruby/error_highlight/pull/58

https://github.com/ruby/error_highlight/commit/9ddc1f31a9

In practice you will likely only end up in this situation if you previously had pre-1.0 prism installed and upgrade Ruby to a version with Prism as the default parser.
