ghostel-kitty: ensure scale of kitty images to avoid cropping

[pank]

Emacs tries to match the height of kitty images to the surrounding text is scale isn't set due to create-image:

create-image is an autoloaded native-comp-function in ‘image.el’.
...
If the property ‘:scale’ is not given and the display has a high
resolution (more exactly, when the average width of a character
in the default font is more than 10 pixels), the image is
automatically scaled up in proportion to the default font.

without the patch:

with the patch:

this is using ghostel v0.43.0 on windows.

Thanks for the PR. The kitty graphics support needs a lot of love, but this at least fixes the immediate issue. My plan is to rewrite the code soon.

I will continue to keep an eye out and test various bits and pieces around this. it's very exciting!

But I mostly use these things on my windows machine, and it remains to be seen if I can make zig actually compile. ($corp laptop acts like it has seen a ghost whenever something ends in .exe)
