text: Title: [BUG] Basic code from documentation does not work
  Body: I tried both the codes described below from the [official docs](https://einops.rocks/api/repeat/) and it does not seem to work
  
  ```
  # change it to RGB format by repeating in each channel
  >>> repeat(image, 'h w -> h w c', c=3).shape
  (30, 40, 3)
  
  # repeat image 2 times along height (vertical axis)
  >>> repeat(image, 'h w -> (repeat h) w', repeat=2).shape
  (60, 40)
  ```
  
  I get the following errors
  ```
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<__array_function__ internals>", line 198, in repeat
  TypeError: repeat() got an unexpected keyword argument 'c'
  ``` 
  and 
  ```
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<__array_function__ internals>", line 198, in repeat
  TypeError: repeat() got an unexpected keyword argument 'repeat'
  ```
  
  Since it is the official documentation code, I thought it is better to ask here and  get a quick answer instead of asking stackoverflow (none of the chatbot fixes worked). Below is the version of einops I have:
  ```
  pip show einops
  Name: einops
  Version: 0.8.0

  Please let me know how to fix this, I'm in a bit of hurry.
