You could do it as a JavaScript userscript if you want it to automatically replace links in your browser rather than manually transform them in an external program one at a time. You can run this in the browser console to test it or save it in Tampermonkey or a similar extension to have it always active:

const goglinks = document.querySelectorAll("[href*='gog.com/game']");
goglinks.forEach((link) => {
let url = new URL(link.href);
link.href = "https://af.gog.com" + url.pathname + "?as=1636858786";
});
