cmd/go: only add a 'go' directive on 'go mod tidy' or when a conversion occurs If the go.mod file exists and is empty, we initialize it from any of various formats supported by legacy dependency-management tools. We also initialize the 'go' directive at that point: we know that the go.mod file is incomplete, because it does not reflect the information in the legacy configuration file, and since we know that the go.mod file is incomplete, we should complete it with as much information as we have — including the version of the language currently in use. However, if there is no legacy configuration file present, then we cannot infer that the go.mod file is incomplete: it may correctly specify a module without external dependencies. In that case, we should not initialize the 'go' directive either: the user will not be expecting unnecessary edits to the go.mod file, and we generally do not make unnecessary-but-helpful edits unless 'go mod tidy' is invoked explicitly.
