Add proper Bookmark button to status action buttons

Why I made this: Currently, Husky has a dedicate Bookmark button which marks for easy bookmark marking and removing. I find this feature really useful, but on pleroma-fe it's hidden away in the extra_buttons menu. One of my users told me they didnt even know pleroma-fe had a Bookmark feature.

Here's how Husky's looks:

And here's how this implementation looks:

I find the code is cleaner than the original as well because it's more based on the retweet/favorite buttons.

Also, very important: bookmark button go spinny

Tested working on my live instance, as well as through npm run dev, no known issues
