How to send all results to trouble.nvim?

[quantum-booty]

I'd like to achieve the following workflow:

1. search files
2. press <c-t> to send all selected items to trouble
3. close fzf-lua and open trouble
   This example works for selected items, not all items.

You can use the same action mentioned in #431 but also send a select-all commands to fzf, for example:

require'fzf-lua'.setup {
  files = {
    actions = { ['ctrl-t'] = { fn = _G.my_action, prefix = 'select-all+' } },
  }
}

EDIT: Btw, you can also invert selection with toggle-all, see #807, and man fzf and search for AVAILABLE ACTIONS to understand how/why this works.
