Fix T94594: Incorrect spreadsheet data set region type in old files

This completes 1a721c5dbec928b0e by versioning old files to correct the
region type. The "tools" region type is relatively standard for this type
of region and doesn't require any changes to the theme, unlike
the "nav bar" type, which would have been a reasonable choice.
