fix: ata return type

[antfu]

It actually returns a Promise. Would be nice to provide that info so users could await for it to resolve.

TypeScript-Website/packages/ata/src/index.ts

Lines 56 to 60 in c8b2ea8

	return resolveDeps(initialSourceFile, 0).then(t => {
	if (estimatedDownloaded > 0) {
	config.delegate.finished?.(fsMap)
	}
	})

LGTM but will require a package release.
