fix(remove-forward-ref): mark ref as optional in type intersections

[iamakulov]

The codemod now generates type & { ref?: RefType } instead of type & { ref: RefType } to correctly reflect that refs are optional.

Otherwise, code like this:

const VolumeIcon = React.forwardRef< React.ElementRef<typeof Svg>, React.ComponentPropsWithRef<typeof Svg> >(({ width = "20", height = "20", ...props }, ref) => { ... } <VolumeIcon /> // ← works

gets code-modded into code like this:

const VolumeIcon = ({ ref, width = "20", height = "20", ...props }: React.ComponentPropsWithRef<typeof Svg> & { ref: React.RefObject<React.ElementRef<typeof Svg>>; }) => { ... } <VolumeIcon /> // ← fails with `Property 'ref' is missing in type '{}' but required in type '{ ref: RefObject<SVGSVGElement>; }'`

and requires manual fixing.
