Admin: Add description in the analytics dashboard on the content of each report option

[vickyszuchin]

Issue description

Provide description in the analytics dashboard on the content of all reports, for example, the exclusions of Unknown and Deleted domains.

One example, the Current full only shows what is currently in the registry. Deleted and Unknown domains don’t exist in the registry and thus they are not shown in this report.

In our implementation, if a Domain is in Unknown, the domain user has not provided DNS info yet. It does not exist in the .gov registry’s zone file yet. The domain is only added to the zone file once the user goes to "Manage the domain". The Unknown state provides analysts a brief cushion in case of accidental approval. It allows the system to revert approvals easily.

Acceptance criteria

• [ ] Draft content for description for each of the three report options (or ONE descriptive text that explains them all)
  • Most of the content is drafted, see
  • https://github.com/cisagov/dotgov-data?tab=readme-ov-file#gov-data
  • https://get.gov/about/data/
• [ ] provide description in the analytics dashboard on the content of each report, for example, the exclusions of Unknown and Deleted domains in Current full.
• [ ] Create dev ticket to add the text

I'm moving this back to the backlog! Not a priority for work right now. I added a link to my very cursory draft.
