Resize Image/Mask (Comfy Core) - scales uniformely instead of scaling height

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

- the Resize Image/Mask node intends to scale in one of the dimensions hieght or width

### Actual Behavior

- you set it it to scale mask height, and it scales mask uniformly in every dimension instead of scaling in 1 chosen dimension

### Steps to Reproduce

draw a mask, take Resize Image/Mask node and preview after scaling on 1 of the dimensions (scale height or scale width) it

_No response_

Start with the Comfy Core Resize Image/Mask node and reproduce the reported workflow: draw a mask, set scaling to height or width, and preview the result. Verify whether the selected dimension changes independently rather than scaling uniformly, and confirm the corrected behavior for both height and width.
