Alias function for is_ratelimited

Hey,

Is_ratelimited is a great function, but the name is quite missleading for incrementing. You'd expect it only to be a boolean, but yet it can also increment. That's great, but I feel we should have also a new function like increment_ratelimit or some sort of increment function which is just a function rather than decorator, that allows you to increment whenever.

At the moment I want to only increment the ratelimit when the user does an unsuccessful login attempt. So i have

is_ratelimited(
                request, group="login_incorrect", key="ip", rate="5/5m", increment=True
)

But instead of that, i'd quite like something like:

increment_ratelimit(request, group="login_incorrect")

Instead i've created my own function that just does the same thing, but it'd be nice to see this in the official version.

Or I may have just missed it 🤷‍♂️

Happy to hear opinions, let me know if i'm just being blind :)
