Followup to https://github.com/ruby/prism/pull/3827 It sets the start to the opening but it should instead just continue on as usual. Fixes https://github.com/ruby/prism/issues/3851 Notice how the AST actually contains "123" in both the body and end keyword. https://github.com/ruby/prism/commit/8f69c5af08
