[FEATURE]: Introduction of vulnerability type

## Describe the feature

I want to be able to describe not just security vulnerabilities in my software but also functional vulnerabilities ie defects and have this information available for release notes.

## Possible solutions

Introduction of an optional field for vulnerabilities -> vulnerabilityType which is an enumeration of security, functional & presentational

## Alternatives

Use custom properties

## Additional context

I am attempting to produce release notes using a SBOM hence wishing to be able to Populate the SBOM with defects recorded in our issue tracker (jira).
