`builder.create()` is async, which makes the docs [here](https://milkdown.dev/docs/api/crepe#using-crepebuilder) misleading, as ```typescript // Create the editor const editor = builder.create() ``` will NOT do what one thinks it would. Also makes unclear how to use it where a sync editor builder is expected, e.g. [with Vue](https://github.com/orgs/Milkdown/discussions/2151).
