any way &group can be added too? Seems like it's the only other missing attribute

Definitely, just did that. Part of me wants to just highlight anything starting with & as an attribute, but that would produce slight weirdness if people don't add spaces around their binary operator & uses 🤷.

I mean it's already weird with something like

event zeek_init() {
    local log = 1;
    local anded = 2&log;
}

but that doesn't really matter much :)
