Variable traverse`Const`

traverse: {
forFile: ((dir, file) => Promise<Optional<string>>);
forFileSync: ((dir, file) => Optional<string>);
} = ...

These methods were moved from the deprecated 'fs' module in v2 and are only used in sfdx-core above

They were migrated into the 'traverse' constant in order to stub them in unit tests
