Interpolations should not be parsed in quoted heredocs

[aibaars]

The following heredoc is wrongly parsed. It looks like the single quotes have no effect.

x = <<'NO_INTERPOLATION'
This should not be interpolated #{interpolation}
NO_INTERPOLATION

program [0, 0] - [4, 0])
  assignment [0, 0] - [0, 24])
    left: identifier [0, 0] - [0, 1])
    right: heredoc_beginning [0, 4] - [0, 24])
  heredoc_body [0, 24] - [2, 16])
    interpolation [1, 32] - [1, 48])
      identifier [1, 34] - [1, 47])
    heredoc_end [2, 0] - [2, 16])

I think it should be

program [0, 0] - [4, 0])
  assignment [0, 0] - [0, 24])
    left: identifier [0, 0] - [0, 1])
    right: heredoc_beginning [0, 4] - [0, 24])
  heredoc_body [0, 24] - [2, 16])
    heredoc_end [2, 0] - [2, 16])
