Update CookieStorageAccessor.js

Proper method for get

[hevilhuy]

This seems would not work with the form

[ntorgov]

this is same function, differ only in spliting aility. it does not work with any forms

export function get(key)
{
     return document.cookie.split("; ")
         .find((row) => row.startsWith(key + "="))
         ?.split("=")[1];
}

instead of

 export function get()
 {
     return document.cookie;
 }
