Add triggering filter to alert embed title

[Etzeitet]

The current alert embed for a triggered filter puts the filter type in the main body, where it's easily missed - especially for those of us who have higher-res screens.

Having the triggering filter in the embed's title will give instant access to that information at a glance. Below image is a mockup of what I propose:

I am not precious about the exact formatting of the title, as long as the information is in there.

I am in favor.

All of our filters are prefixed with filter right ?

If you want, I could send a PR for this @Etzeitet.

As for implementation we could split based on the underscore then build the title and the type of filter from there.
OR, we could add a key that can hold a descriptive name for each filter.
What do you think ?
