fix(list): Add uuid for each list item

[yasincaliskan]

Description

• Install uuid package to generate unique IDs.
• If not provided listItemKeyGenerator or testid props, generates uuid.
• Also, generating a key with testid is not best practice. Because if list manipulate (add/remove an item or changing order) causes using wrong keys.

I think we should re-arrange the ifs:

   if (listItemKeyGenerator) {
          key = listItemKeyGenerator(item, listItemTestId);
          // @ts-ignore
    }  else if (item && typeof item === "object" && item.id) {
        // @ts-ignore
        key = item.id;
        }  else {
          key = uuidv4();
        }

Because I believe currently we don't use id in any case. We override the first if in 43 in the else in 50.
Also I think it's time to create a util for this and clean up the component function body:

        return <Fragment key={generateListItemKey({
          item, listItemTestId, listItemKeyGenerator
          })}>
          {children(item, listItemTestId, index)}
        </Fragment>;
