Upgrade html2canvas to html2canvas-pro in order to support the oklch() color function.

html2Canvas does not support several modern color functions, leading pdf output to fail when using a few modern UI frameworks such as DaisyUI.

e.g: daisyui@latest uses oklch color function, If we use jsPDF with daisyUI we facing an error Error: Attempting to parse an unsupported color function "oklch"

Also, html2canvas-pro has several advantages over html2canvas, including:

• support color function color() (including relative colors)
• support color function lab()
• support color function lch()
• support color function oklab()
• support color function oklch()
• Support object-fit of <img />
