🎚️ fix: Google top_k Slider Step to Integers

[danny-avila]

Summary

I adjusted the step value for the Google topK slider from 0.01 to 1, ensuring integer-only selections for this parameter.

• Modified the googleSettings object in schemas.ts
• Changed the step property of the topK setting from 0.01 to 1
• Maintained the existing min (1), max (40), and default (40) values

Closes #4403

Change Type

• Bug fix (non-breaking change which fixes an issue)

Testing

To test this change:

1. Navigate to the Google model settings in the UI
2. Locate the topK slider
3. Verify that the slider now moves in whole number increments
4. Confirm that the minimum (1), maximum (40), and default (40) values remain unchanged
