Add the ability to delete feeds based on a text filter in Akregator

I think that in a world full of information and distractions it would be nice to have a way to filter our certain things.

For example, you could do things like auto delete things related to a website you are not interested in, or let’s say you don’t want to see clickbait articles involving your “favorite” politician or a celebrity etc. Or getting rid of YouTube shorts.

I think this kind of functionality would be a great addition to the RSS reading experience.
