Remove deprecated `_exportable_id` parameters from vulnerability export workers
As we can not directly remove the redundant parameters from the VulnerabilityExports::ExportWorker#perform
and VulnerabilityExports::ExportDeletionWorker#perform
, I've just deprecated them with default values. After we ship the feature, at some point we have to delete those parameters entirely.
For more information and background please check the comment
