Feature Request: Last Updated Date field (for the vendor's update timestamps)

[JimmyKip]

Environment

• Nautobot version: N/A
• nautobot-plugin-device-lifecycle-mgmt version: latest

Proposed Functionality

For CVE / Hardware Notices / Software Notices include a field to record the date the notice was updated by the vendor.

Use Case

Vendor's will often publish a notice, and then update it at later dates. Including the date of last update within the lifecycle plugin in Nautobot allows for automated confirmation that the notice is up to date, or a flag if it has been updated by the vendor.
