fix(plugin-import-export): translated preview labels (#11758)

### What?

The import-export preview UI component does not handle localized fields
and crash the UI when they are used. This fixes that issue.

### Why?

We were not properly handling the label translated object notation that
field.label can have.

### How?

Now we call `getTranslation` with the field label to handle language
keyed labels.
