refactor(logVersion)!: avoid onAfterConfigResolve

previously, cli.ts was injecting onAfterConfigResolve solely to print
the version banner. Now, build() itself will log the version after
resolving the config, unless the caller has supplied a different
onAfterConfigResolve.

BREAKING CHANGE: callers of vitepress' build() will now notice the
version banner gets printed. To disable that, pass a noop function:

```ts
build(root, {
  onAfterConfigResolve() {},
})
```
