Remove notification window.

[niksingh710]

I am aware of notify.dismiss()
but if i use Telescope notify and then select anotification it focuses on that notification window.
The problem is if i focus other window by c-h or my key maps then i can't focus back to the notification window and can't close it.

it becomes quite annoying sometimes.
have to use mouse to focus and then close.

it will be fine if i can close that window or open notification content in new buffer. or in a split.
