如何通过javascript从html页面中的特定github txt文件中获取数据

我想获取这个网址的数据https://github.com/ProjectSakura/OTA/blob/10/changelog/changelog_beryllium.txt#L2

我正在尝试使用 fetch api 来获取数据,但我收到了 cors 错误

这是我想要做的

async function showmodal1() {
    console.log("hello")
    const data = await 
                 fetch('https://github.com/ProjectSakura/OTA/blob/10/changelog/changelog_beryllium.txt');
    console.log(data)
}
showmodal1();
