feat: Added "Silent" theme

[torbratsberg]

Simple theme for quick operations where you barely need to look at the Telescope window.

I like it, can imagine this really well for LSP code actions. Bonus points if we figure out how to place the popup relative to the current cursor location.

[torbratsberg]

@disrupted I agree! I couldn't find a way to set it relative to the cursor with the current configuration options, but that was the initial plan.

Isn't this just require('telescope.themes').get_dropdown{ previewer = false } with a different result_height? Also might be interesting for you but there is a huge refactor of how layouts work here: #823

[tjdevries]

Yeah, this seems very close to the dropdown theme?

[torbratsberg]

It is very similar to the dropdown theme, but intended to be used for smaller and quicker actions. I just saw this PR #878 which has almost the same theme as Silent, but relative to the cursor which is probably a better layout for this kind of theme. So this PR can be closed.

There's an open PR for cursor relative positioning - #878
