[FW][FIX] package: correctly name package entry files

[fw-bot]

Files are named o-spreadsheet[...] in package.json but rollup generates o_spreadsheet[...] files

as a result any import fails because it's looking for a file that doesn't exist

import { Model } from @odoo/o-spreadsheet

=> Error: Cannot find module '/home/odoo/odoo/upgrade-spreadsheet-data/node_modules/@odoo/o-spreadsheet/dist/o-spreadsheet.cjs.js'.
Please verify that the package.json has a valid "main" entry
