Warn when escaping interpolation in heredocs to use the quoted heredoc form instead. This shouldn't warn when the heredoc is also interpolated.

<<-DOC
# ^^^^ error: Use `<<-`DOC`` instead of `<<-DOC` to automatically escape interpolation
Here is how you interpolate strings: "\#{thing}".
DOC

# Should be:
<<-'DOC'
Here is how you interpolate strings: "#{thing}".
DOC

(GitHub syntax highlighting for Crystal should probably also be updated to support this at some point, or just have them move to the tree sitter)
