update fixed version field

[DmitriyLewen]

Description

There are cases, when package has fixed versions for vulnerability, but last major version has no fix.
When we scan the latest major version, Trivy shows the fixed versions for previous versions.
This can be confusing.
Perhaps we need to change logic to show fixed version.

Example for better understanding:
CVE-2021-23214 fixed versions:

• ">=0, <9.6.24",
• ">=10.0, <10.19",
• ">=11.0, <11.14",
• ">=12.0, <12.9",
• ">=13.0, <13.5",
• ">= 14.0"

When scanning version "15.4.0" we got the following result:

┌────────────┬────────────────┬──────────┬────────┬───────────────────┬──────────────────────────────────┬────────────────────────────────────────────┐
