Update props spread, fix fill color, fix props type inference

[mtonc]

Changed const size = Astro.props.size to const { size, ...props} = Astro.props and then on the component changed {....Astro.props} to {...props}. This was causing certain properties to be overwritten and now will preserve any other SVG attributes passed in such as stroke.

Also updated the build.js file to only replace the color comment and not the full fill=<!--color-->;

Changed export type Props to import type Props so type-hinting could be inferred and allow SVG props to be passed in.

Also changed the 'currentColor' on the fill. No color was set on a parent element, so this was not doing anything.
