Ability to choose a previewer similar to typst-preview.

[scientiac]

Motivation

typst-preview.nvim has an option called:

 open_cmd = '<browser/app> %s'

this makes it possible to choose a browser to open the URL instead of opening the URL in the default browser.

Description

While it can be used for neovim, in helix I cannot pass a open_cmd to preview.background.args, it would be a handy feature to have to use a previewer different from the default browser.
