Convert command bug for vulnerability versions affected status

[tommyrousey]

The convert command expects "not_affected" instead of "unaffected" when converting json to another format. This is in opposition to the validate command, which expects "unaffected".

To convert, I have had to sed unaffected to not_affected and then run the convert command. I've attached a screenshot of the terminal

Note: the validate command rejects the one that can be converted

This is also true for the merge command

vulnerabilitiesType: "unaffected" would be the correct value.
This is wrong here:
