Add OWASP Top 10 2021/2017 columns to CSV vuln report export
## Release Notes
There are multiple columns for OWASP Top 10 identifiers (2017, 2021) available for users, which makes it easier to filter.
## Problem to Solve
Today, both OWASP Top 10 2017/2021 are located in a column in the CSV report named "Other Identifiers". This makes life harder for users who want to filter or sort the report based on it.

## In Scope
The desired result is to have two additional columns:
* OWASP Top 10 2021
* OWASP Top 10 2017
## Out of Scope
None
## Designs
None
## Dependencies
* TBD
