Bug: diagnostic api change not work in neovim 0.10.

Link Issue: https://github.com/AstroNvim/AstroNvim/issues/2603

It is normal after disable_defaults = true is set. It is caused by the diagnostic api change of neovim 0.10

You may need to define your own signs table here. go.nvim already using diagnostic.config to setup signs, which comply with neovim 0.1x requirements.

  diagnostic = { -- set diagnostic to false to disable diagnostic
    hdlr = false, -- hook diagnostic handler and send error to quickfix
    underline = true,
    -- virtual text setup
    virtual_text = { spacing = 0, prefix = '■' },
    update_in_insert = false,
    signs = true,  -- use a table to configure the signs texts
  }
