Adapat to new alocation API

Perhaps check the version of Cinnamon before applying the new API?

@Sunderland93 This won't work unfortunately, you would need to version the applets. For example with sticky@scollins, you'd need to create a new directory sticky@scollins/files/sticky@scollins/6.8 and copy all the files from sticky@scollins/files/sticky@scollins/3.2 into /6.8 and make the changes to the version in /6.8

An alternative way would be to use version_exceeds() in util.js

For example in sticky@scollins/files/sticky@scollins/3.2/applet.js

allocate(actor, box, flags) { 
    let childBox = new Clutter.ActorBox();

    childBox.x1 = box.x1;
    childBox.x2 = box.x2;
    childBox.y1 = box.y1;
    childBox.y2 = box.y2;

    const CINNAMON_VERSION = imports.misc.config.PACKAGE_VERSION;
    if (Util.version_exceeds(CINNAMON_VERSION, "6.8")) {
        this.textBox.allocate(childBox);
    } else {
        this.textBox.allocate(childBox, flags);
    }
}

The allocate(actor, box, flags) { line should be fine as flags would just be undefined in cinnamon 6.8
also, Util.version_exceeds should really be called version_same_or_exceeds or version_at_least
