Resolve "OnePlus Version warning"

Description

Temporarily: not offering flash on OnePlus if the currently installed ROM version is different from Android 11

Issue(s)

Closes #461

Tests

The whole logic is in this function from DeviceDetectedController.java.
It will have to be replaced in the short term by something more evolutionary than static code, probably server side in an API for more flexibility.

    private boolean isIncompatibleVersion(Phone phone) {
        try {
            if (phone.getManufacturer().toLowerCase().equals("oneplus") &&
                phone.getAndroidVersion() != 11) {
                    return true;
            }
        } catch (Exception e) {}
        return false;
    }

getManufacturer comes from => "ro.product.manufacturer"

getAndroidVersion comes from => "ro.build.version.release"
