This limits front matter fields to "Status" and "Minimum Server Version".

Spec versions were removed across the board, excluding the Unified Test Format, which retained a field for "Current Schema Version". The only other spec where versioning was somewhat relevant was Extended JSON, and the transition from 1.0 to 2.0 is clearly noted in the changelog (minor versions since 2.0 were not relevant).

Apart from the deprecated Bulk API spec, all specs have an "Accepted" status. Some were incorrectly listed as "Draft".

This also revises changelogs across all specs to use "Field List" formatting (like spec front matter). The CSFLE and Change Stream specs were left as-is, since they used CSV and grid tables, respectively. Some existing changelog entries were incorrectly ordered and fixed. Lastly, specs were inconsistent in whether changelogs entries used ascending or descending date order, so existing order was left in place when possible. For some very old specs without dated changelog entries, dates were inferred from git history.
