[Bug]: Field definition for field "key" not found.

[DuckThom]

Expected behavior

System fields can be imported

Actual behavior

System fields, such as 'key' cannot be imported as they don't have a field definition.

Steps to reproduce

Pimcore: 11.1.1
Data importer: 1.8.5

1. Create a data import job
2. Map something to "SYSTEM Key"
3. Run import
4. Item cannot be imported due to the following error:
