chore: rename column in site explorer report (#2592)

## Description
Change "Preingt State" label in forge-admin-cli site-explorer
get-report-endpoint => "Pre-ingestion State".

`| Preingt State | Serial Number  | Last Exploration Error |
`

The other column headers are all spelled out, "Preingt" isn't obvious in
meaning and so spell it out, too.
