feature: is there any way to support transparent background?

[ZovutVanya]

Did you check the docs?

• [x] I have read all the drop.nvim docs

Is your feature request related to a problem? Please describe.

So I have drop activate on the Snacks dashboard when I enter neovim. It adds a black window with a border

Describe the solution you'd like

It would be nice if we could make it transparent and disable the border for this particular window

Describe alternatives you've considered

I can disable the borders altogether, but I like them in other contexts
