Formatter crash when heredoc contains string interpolations and do-end block

[shootingfly]

Error was happened when I formatted a heredoc that contains do-end block and Interpolation.
It works if there are not interpolations in do-end block.

crystal tool format --show-backtrace /home/rocky/Workspace/Crystal/jbuilder/src/jbuilder/embedder.cr

embedder.cr

puts <<-Crystal
  Jbuilder.new do |json|
    #{File.read(ARGV[0])}
  end.to_json
Crystal

Mmh, #9362 redux? /cc @makenowjust :)

do ... end is not important. We can reproduce it on the following:

puts <<-FOO
foo
#{1}
FOO

The second (or more) line interpolation inside no indent heredoc causes this bug.
