ObsidianPasteImg never works.

### 🐛 Describe the bug

Whenever using this command it says no image data in the clipboard.

### Config

```lua
return {
"epwalsh/obsidian.nvim",
version = "*",
lazy = true,
cmd = "ObsidianQuickSwitch",
ft = "markdown",
keys = {
{ "wW", mode = "n", "ObsidianQuickSwitch", desc = "Obsidian Notes" },
},

-- Replace the above line with this if you only want to load obsidian.nvim for markdown files in your vault:
-- event = {
-- -- If you want to use the home shortcut '~' here you need to call 'vim.fn.expand'.
-- -- E.g. "BufReadPre " .. vim.fn.expand "~" .. "/my-vault/**.md"
-- "BufReadPre path/to/my-vault/**.md",
-- "BufNewFile path/to/my-vault/**.md",
-- },
dependencies = {
-- Required.
"nvim-lua/plenary.nvim",
"hrsh7th/nvim-cmp",
"nvim-treesitter/nvim-treesitter",
"3rd/image.nvim",
-- see below for full list of optional dependencies 👇
},
opts = {

},
daily_notes = {

},
attachments = {
img_folder = "Images",
},
follow_url_func = function(url)
print("Opening URL: " .. url)
vim.fn.jobstart({ "xdg-open", url }) -- linux
end,
workspaces = {
{
name = "personal",
path = "~/Code/Obsidian/",
},
},
pickers = {
name = "fzf-lua",
},
},
}
```

Start by reproducing the ObsidianPasteImg command on Linux with an image in the clipboard, using the supplied obsidian.nvim configuration and checking the listed image.nvim dependency. Trace the command's clipboard handling and confirm completion by saving the clipboard image under the configured Images attachment folder instead of reporting that no image data exists.
