When spacetime dev (or publish) can't find the module directory, the error was: Could not detect the language of the module. Are you in a SpacetimeDB project directory? Now shows the actual path that's missing: Module directory does not exist: '<path>'. Check your --module-path flag or the module-path setting in spacetime.json.

dismissing my review because I'm waiting for another approval and I don't want the bot merging this prematurely

When
spacetime dev(orpublish) cannot find the module directory, the error was:This is confusing because the real problem is the directory does not exist, not that the language cannot be detected.
