Keyboard Manager: incorrect Russian translation

### Microsoft PowerToys version

0.99.1

### Utility with translation issue

Keyboard Manager

### 🌐 Language affected

Russian

### ❌ Actual phrase(s)

"вставки" (genitive)

### ✔️ Expected phrase(s)

"Вставляет" (the corresponding verb in 3rd person singular present tense, "inserts").
Or "вставка" (the noun in nominative), but with a colon directly after the key designation.

### ℹ Why is the current translation wrong

There is no reason to put this word in genitive.

No file or test is named. Locate the Russian Keyboard Manager localization resource and the string shown in the screenshot, then compare its surrounding key and context with the reported alternatives. Done means the incorrect genitive form is replaced with the agreed Russian wording and the localization still loads correctly.
