Use vips methods for resizing instead of ImageMagick

[dunkOnIT]

The RO's page is currently broken with this error:

Reproducing in terminal, it is because of this resize code in line 33 of the RO controller:

logo.variant(resize: "500x300").processed

After LLM discussion, it seems that we are using an ImageMagick method but we have changed to vips. Using vips-specific syntax, I was able to get the resize to work without error in the console:
