system clipboard support

[doodleEsc]

yank in nvim works perfect, but the content copied from system to the register * and + does not show in telescope

this my config for clipboard-provider

  vim.g.clipboard = {
    name = "myProvider",
    copy = {
      ["+"] = "clipboard-provider copy",
      ["*"] = "clipboard-provider copy",
    },
    paste = {
      ["+"] = "clipboard-provider paste",
      ["*"] = "clipboard-provider paste",
    },
    cache_enabled = 0
  }

clipboard-provider copy will send content to all the copy tools, such as pbcopy, xclip clipboard-provider paste will paste content and return as long as the one of the tools works.

right now, nvim to system works fine, telescope will show register content. But system to nvim not works, telescope do not show register content.
