[FIX] web_editor: override fonts in reports

Fixes odoo/odoo#27487
Noto Color Emoji produces an error on wkhtmltopdf, cf
wkhtmltopdf/wkhtmltopdf#4149

In the backend assets, the $font-family-sans-serif is changed in
web/static/src/scss/bootstrap_overridden.scss

In the reports assets, the $font-family-sans-serif was NOT changed in
web_editor/static/src/scss/bootstrap_overridden.scss

The default boostrap fonts were still used in reports, ignoring the changes made
for backend.

closes odoo/odoo#32312
