TODO: to make it easy to find for which operating mode the save_and_submit_button has become obsolete
detect if Superpower ChatGPT is enabled for Chrome and Firefox.

This only works for Chrome within a userscript:

const extensionId = 'amhmeenmapldpjdedekalnfifgnpfnkc';
const resourcePath = 'icons/info.png'; // This works
//const resourcePath = 'manifest.json'; // This doesn't work due to restrictions
const imgUrl = `chrome-extension://${extensionId}/${resourcePath}`;

fetch(imgUrl)
    .then(response => {
        if(response.ok) console.log('Extension installed:', true);
        else throw new Error('Resource not accessible');
    })
    .catch(error => console.log('Extension installed:', false));

Since Firefox doesn't have a similar method that I know of, it's better to
check for an element that has been injected by Superpower ChatGPT (Auto Sync ON/ OFF)
for both Chrome and Firefox.
