Associate finding explanation to finding ID in docs

[lorengordon]

Add a table to the findings index to make it easier for users to lookup a finding by the finding ID (CVE and STIG to start). Something like:

| Finding Explanation | Finding IDs                         |
|---------------------|-------------------------------------|
| <link to heading>   | <list of known-related finding IDs> |
