Ability to close editors with keyboard on :ls

[vchernetskyi993]

Is your feature request related to a problem? Please describe.
When listing active editors using :ls, there is an X button to close editors without opening them. I wasn't able to find/configure a shortcut to do the same with keyboard (i.e. closing a highlighted editor without opening it or using mouse).

Describe the solution you'd like
To use some keybinding to execute "Close Editor" action from the editor picker (e.g. letter d similarly to d in :bd).

Describe alternatives you've considered
Obviously, we can close editors with many different commands after switching focus to it. However, I'm used to cleaning up my open editors periodically (e.g. after some logical part of a task was done) and it's a bit tedious to open-close all of them or using :bd <n> (especially since <n> changes after each closure).
