A method that was incorrectly named to suggest it deletes spreadsheet revisions has been removed and simplified. The method actually archives revisions rather than deleting them, and since the version history feature was added, permanent deletion is no longer possible. The single-line method has been inlined into the code for better clarity.

The method named `_delete_spreadsheet_reviions`:

- the method archives instead of deleting
- since the version history feature, we CANNOT delete them.

Since it's only a single line, it can be inlined.
