feat(fortifyExecuteScan): added conversion to SARIF for FPR files (#3485)
* feat(FPRtoSARIF): boilerplate & comments

* Feat(Ingest): Build done, Vulnerabilities partway

* feat(Vulnerabilities): now entirely parsed

* feat(Ingestion): handle Description object

* feat(FprToSarif): integration in Piper step, full xml structure

* feat(fpr_to_sarif): base program. Need to replace names in messages

* feat(fpr_to_sarif): message substitution and custom definition integration

* fix(fpr_to_sarif): missing replacement in tools object

* fix(fortifyExecuteScan): unit tests

* fix(fpr_to_sarif): failing unit test

* Fix fortify folder creation for generating sarif

* deletion of unzip folder

* fix(fortifyExecuteScan): change logging to info

* feat(fpr_to_sarif): better unit test

* fix(fpr_to_sarif): pr tests failing

* feat(fpr_to_sarif): add specific properties to sarif

* feat(fpr_to_sarif): severity integration

* fix(fpr_to_sarif): unit test fixed
