There's something we do in Config: we replace env placeholders with credible values. The goal of the command is not to prove a theoretical point but to help spot errors quickly. We should skip instead. |

Added comments because those things are kind of hard to follow. We actually don't need to resolve the value here since we only care about the type.

3 cases here (with param: "%env(FOO)%":
- only 1 env placeholder (eg:
%param%) -> we try to resolve it to get its type. - more than 1 chained env placeholder (eg:
%param%%param%) -> it has to be a string - mixed env placeholder with a string (eg :
foo%param%) -> it has to be a string
