":Gitsigns setqflist all" does not work as intended

[rv-ragul]

Description

The documentation says
:Gitsigns {subcmd} {args} is equivalent to :lua require('gitsigns').{subcmd}({args}).

However, :lua require("gitsigns").setqflist("all") works but :Gitsigns setqflist all does not work. It returns the qflist for the current buffer.
And I found out the bug, In the file lua/gitsigns/actions.lua, exactly at line number 1234, args[2] is processed for the target parameter of gitsigns.setqflist(target). This is wrong. We have to check for args[1].

What I did...
when ":Gitsigns setqflist all" is run, args parameter in line 1233 will have the values as "{ 'all' }", there is no second value in args.

Now I changed args[2] to args[1] in line 1234, Now everything works fine.

We have to just alter only one line of code to fix the issue. I tried to make pull request but I dont know how to do it although I have git experience for 2 years

Neovim version

NVIM v0.10.0-dev-1318+gf5eabaa94 Build type: RelWithDebInfo LuaJIT 2.1.1696795921

Operating system and version

Expected behavior

The args[1] should be used for target instead of args[2]

Actual behavior

:Gitsigns setqflist all only returns the qflist of current buffer

Minimal config

for name, url in pairs{
  gitsigns = 'https://github.com/lewis6991/gitsigns.nvim',
  -- ADD OTHER PLUGINS _NECESSARY_ TO REPRODUCE THE ISSUE
} do
  local install_path = vim.fn.fnamemodify('gitsigns_issue/'..name, ':p')
  if vim.fn.isdirectory(install_path) == 0 then
    vim.fn.system { 'git', 'clone', '--depth=1', url, install_path }
  end
  vim.opt.runtimepath:append(install_path)
end

require('gitsigns').setup{
  debug_mode = true, -- You must add this to enable debug messages
  -- ADD GITSIGNS CONFIG THAT IS _NECESSARY_ FOR REPRODUCING THE ISSUE
}

-- ADD INIT.LUA SETTINGS THAT IS _NECESSARY_ FOR REPRODUCING THE ISSUE

Steps to reproduce

1. nvim --clean -u minimal.lua
2. Go to git repo with changes in multiple files
3. Run :Gitsigns setqflist all

Gitsigns debug messages

:Gitsigns debug_messages
cli.run: Running action 'setqflist' with arguments { "all" }

I added first two lines, As you can see, args has only one argument.
