Improve type hints of from_url method for async Redis client.

[cheizdo2-art]

Description

Improve type hints for from_url() method for Redis client in asyncio module.

Motivation

Up until recently, redis.asyncio.client.Redis.from_url() and redis.asyncio.utils.from_url()
lacked return type annotations, causing MyPy to report no-untyped-call errors when used
in strict typing mode.

This PR improves type safety and IDE autocomplete support for users of the asyncio Redis client.

Changes

• The return type annotation -> "Redis" of Redis.from_url() classmethod is following the pattern of from_pool() method return type hint (already changed with a previous commit)
• Adds type hint for the cls parameter for the same method - again following the pattern in from_pool

Example Usage (Before/After)

Before (requires type:ignore):

import redis.asyncio as redis

async def connect():
    client = await redis.from_url("redis://localhost")  # type: ignore[no-untyped-call]
After (fully typed):
import redis.asyncio as redis

async def connect():
    client = await redis.from_url("redis://localhost")  # ✅ No type:ignore needed
