Add Roborock mop intensity translations

[starkillerOG]

Breaking change

Proposed change

In HA 2025.10.0 two new mop modes were introduced through a bump of the upstream libary after a PR in that upstream library I made: Python-roborock/python-roborock#415
However the translations in the strings.json where not updated for these new modes yet.
This adds the missing translations.
