Remove the ignore rule for project_fingerprint column from the vulnerability_occurrences table

Why are we doing this work

We are in the process of deprecating the usage of the project_fingerprint attribute of the findings. By using uuid values to identify findings, we can easily associate any related entity with finding.

We need to remove the ignore rules added by #342198 (closed) to complete the process of moving to uuid values.

Dependency

• This issue has to be done after the release of #542332 (closed) so please make sure to start working on this after that dependency gets released.
