Is it still possible to disable the diff previewer?

Hi, thanks for the plugin.

I'm currently using the get_cursor theme from telescope. Sometimes the diff window becomes too bulky and overlaps with options from the actions menu:

Hence I would like to disable the diff preview sometimes. A month ago this could be achieved by the following configuration, by passing false to previewer option:

require('actions-preview').setup { telescope = require('telescope.themes').get_cursor { previewer = false } }

Which unfortunately does not work anymore since e4aa224. With the same configuration, the code actions menu pops up still, but selecting an option gives the following error:

Error executing lua callback: ...s-preview.nvim/lua/actions-preview/backend/telescope.lua:100: attempt to index field 'state' (a nil value)
stack traceback:
    ...s-preview.nvim/lua/actions-preview/backend/telescope.lua:100: in function '_teardown_func'
    ...zy/telescope.nvim/lua/telescope/previewers/previewer.lua:78: in function 'teardown'

    ...share/nvim/lazy/telescope.nvim/lua/telescope/pickers.lua:531: in function <...share/nvim/lazy/telescope.nvim/lua/telescope/pickers.lua:530>

A similar error would also arise when trying to quit/close the popup.

Here's an animation showing the chaos:

Having these said I guess that's definitely not how things work now. Is it still possible to disable the diff previewer? If yes, then what would be the correct way to setup so?

Thanks again for your efforts and devotion in the plugin. If you need more information please let me know.

Hmm, just came across #24 according to which disabling the previewer would not be endorsed. I guess I'll be staying with 29724d2 then.

What is the purpose of disabling the preview while using this plugin? If you don't need a preview, you can use other plugins like dressing.nvim. If there is a useful way to use this plugin while disabling the preview, I will consider officially supporting it.

That being said, regressions should always be avoided, so I will fix this issue..

OK, please re-open this issue when you can explain the purpose of disabling previews.

One could disable it when langauge does not support previews while keeping enabled for languages that support it :)

Ah, I see. I will investigate if that is possible.
