CI fails when code that throws an error is marked as crystal-play

[ftarulla]

The CI will compile code-blocks marked with crystal-play.
So when the code-block itself is an example of a compile error (ie. it is suppose to throw an error) then the CI fails.

Example:

def life_universe_and_everything
  "Fortytwo"
end

puts life_universe_and_everything + 1 # Error: no overload matches 'String#+' with type Int32

This code block shows an example of a compile error. And therefore it is supposed to fail when compiled. As expected, when compiled by the CI, it fails.

Maybe we can mark these blocks of code in some way that the CI skips them 🤔

I suppose we could scan for # Error: in the code.
