image-mode uses an obsolete command (29.1)

Hi, 

I keep running into this issue when I H or W on an image with evil-collection.
I'd be happy to contribute a pull request, but I'm not sure which emacs versions this project aims to support.

`‘image-transform-fit-to-height’ is an obsolete command (as of 29.1); use ‘image-transform-fit-to-window’ instead.`
