Describe the bug
The generated gitlab report cannot be parsed by gitlab because of a number of schema validation issues.

1. vulnerability name can be greater than 255 characters (this happens most commonly when the description is used for the name field)
2. description must be present (it is not required in the schema)
3. links without a name or url do not render properly, the latter is invalid as all links must have a url according to the schema

Version of dependency-check used
The problem occurs using version 12.0.2 of the cli

Log file
log file

To Reproduce
Steps to reproduce the behavior:

1. Install version 12.0.2 of the cli or acquire from releases
2. Navigate to a project with the following vulnerable dependencies (as an example): GHSA-g9r4-xpmj-mj65 and GHSA-2cf5-4w76-r9qv
3. Run the command dependency-check.sh --format "ALL" --nvdDataFeed "$DATA_FEED_URL"
4. View the report in dependency-check-gitlab.json

Expected behavior
A json document compliant with the gitlab schema for dependency scanner reports

Additional context
For our project we use a mirror of the nist nvd data feed.
