Russian translate and fix for Fluent plural handling

[SuperSuslik312]

Fix Fluent plural handling for $days and retain red color formatting.

• Pass $days as a number to Fluent for correct pluralization.
• Replace the number in the localized string with a red-colored version
  using the .red() method.
• Ensures both proper plural handling and terminal color formatting.

These changes were implemented due to the specifics of plural forms in the Russian language.
