fix(studio): remove Enterprise-only notice from unified logs preview (#47211)

## Problem

The unified logs feature preview displayed a message saying the
interface was only available for Enterprise plan organizations. The
feature is now available to all plans, making this notice inaccurate and
potentially confusing.

## Fix

Removed the paragraph containing the Enterprise-only restriction notice
from the unified logs preview component.

## How to test

1. Open Studio and navigate to any project
2. Open the Feature Previews panel
3. Find the "Unified Logs" preview entry
4. Confirm the Enterprise restriction notice is no longer shown
5. Expected result: only the description and screenshot are visible,
with no plan restriction text
