docs-reorder: Crash when no i18n specified in payload.config.ts

Error:

 ⨯ node_modules/deepmerge/dist/cjs.js (61:1) @ getKeys

Reproduction:
Make sure there is no i18n section in your payload.config.ts.

Adding this back into payload.config.ts should make the error disappear:

    i18n: {
        translations: {},
    },

I haven't tried beta 63+ with any of my plugins, there definetely were some breaking changes, so I'll need to go through each and fix those
