Invalid DOM property fill-rule in Icons component

[CezarLuca]

I encountered a warning in the console when using the UNDERLINE from COPY_PASTE_LIST.md from this repository:

Warning: Invalid DOM property fill-rule. Did you mean fillRule?

The code from the Icons.tsx in the underline icon component on the other hand is correct.
I propose to change fill-rule to fillRule in COPY_PASTE_LIST.md to be correct and consistent with the production code and eliminate the debugging step for those who code along:

<svg {...props} viewBox='0 0 687 155'>
  <g
    stroke='currentColor'
    strokeWidth='7'
    fill='none'
    fillRule='evenodd'
    strokeLinecap='round'
    strokeLinejoin='round'>
    <path
