#827

This issue covers the improvements to the links from findings flyout to the MITRE website to provide user with additional information of the potential attack.

• 1. Add links to the MITRE pages to the finding view flyout

2. Provide additional links to the tactics in addition to the mitigation techniques.

Currently we're providing the links to the specific mitigation techniques. It would be good for additional context to also identify the tags for the tactics (e.g. attack.exfiltration pointing to https://attack.mitre.org/tactics/TA0010/ ) and add the links to those.
The example below shows one tag being linked, and another one is missing the link.
