836de8b breaks using LSP colors in the custom_highlights

[milch]

Description

I have some custom highlights set up in my config like this:

	custom_highlights = function()
		local lsp = require("catppuccin.groups.integrations.native_lsp").get()
		return {
			Group1 = { fg = lsp.DiagnosticVirtualTextError.fg, bg = lsp.DiagnosticVirtualTextError.bg },
                        -- ... etc. ...
		}
	end,

It seems that this broke with the following commit: 836de8b, and now I get the following error when catppuccin loads:

Failed to run `config` for catppuccin
