`run` attribute missing

[akaihola]

I have a script almost directly taken from README:

import os

from sprites import SpritesClient

# Create a client
client = SpritesClient(token=os.environ["SPRITES_TOKEN"])

# Get a sprite handle
sprite = client.sprite("my-sprite")

# Run a command
result = sprite.run("echo", "hello", capture_output=True)

It fails:

❯ uv pip install sprites-py
