Feat: Implement openURL

[Al0den]

Fix for #310

[tmillr]

Just use vim.ui.open({path}) instead.

No vim.ui.open on

[tmillr]

That's very strange. It's in the docs :h vim.ui.open() and it works for me and im on 0.10.1 as well. You need to run :version from within nvim to check the version.

According to neovim changelogs vim.ui.open has existed since 0.10. Lets use @tmillr suggestion and do something like this:

  ["copilot/openURL"] = function(_, result)
    local success, _ = pcall(vim.ui.open, result.target)
    if not success then
      if vim.ui.open ~= nil then
        vim.api.nvim_echo({
            { "copilot/openURL" },
            { vim.inspect({ _, result }) },
            { "\n", "NONE" },
        }, true, {})
        error("Unsupported OS: vim.ui.open exists but failed to execute.")
      else
        vim.api.nvim_echo({
            { "copilot/openURL" },
            { vim.inspect({ _, result }) },
            { "\n", "NONE" },
        }, true, {})
        error("Unsupported Version: vim.ui.open requires Neovim > 0.10")
      end
    end
  end
}

Super weird, was on 0.10 and didn't have it.
Anyways, changed the commit to include this, thanks!
