Revert "Connect - Relation on FE Importer (#13213)" (#13313)

This reverts commit cc71394863.

Regression introduced in https://github.com/twentyhq/twenty/pull/13213
The import/export use an upsert logic and when it goes through the
"update" path it fails due to the connect not being implemented yet
(should be in https://github.com/twentyhq/core-team-issues/issues/1230)
