surround using lazy opts not working

[Dragit]

Explain the issue

It seems that the surround option is broken in lazy.nvim

1. neovim (NVIM v0.12.3 Build type: RelWithDebInfo LuaJIT 2.1.1780076327) with treesitter

2. Reproduction:
   minimal init.lua, call with nvim --clean -u minit.lua
minit.lua:

    vim.env.LAZY_STDPATH = ".repro"
    load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()
    
    require("lazy.minit").repro({
    	spec = {
    		{
    			"nvim-treesitter/nvim-treesitter",
    			build = ":TSUpdate",
    
    			ensure_installed = { "html", "latex", "markdown", "markdown_inline", "typst", "yaml" },
    		},
    		{
    			"andymass/vim-matchup",
    			lazy = false,
    			---@type matchup.Config
    			opts = {
    				treesitter = {
    					stopline = 500,
    				},
    				surround = {
    					enabled = 1,
    				},
    			},
    		},
    	},
    })

3. matchup should load the <Plug>(matchup-cs%) and <Plug>(matchup-ds%) bindings

4. they are not loaded, however. :echo get(g:, 'matchup_surround_enabled', 0) yields 1
   when I try :map <Plug>(matchup-cs%) and :map <Plug>(matchup-ds%) yields no mappings found

Fix

use

    vim.env.LAZY_STDPATH = ".repro"
    load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()
    
    require("lazy.minit").repro({
    	spec = {
    		{
    			"nvim-treesitter/nvim-treesitter",
    			build = ":TSUpdate",
    
    			ensure_installed = { "html", "latex", "markdown", "markdown_inline", "typst", "yaml" },
    		},
    		{
    			"andymass/vim-matchup",
    			lazy = false,
          init = function()
            vim.g.matchup_surround_enabled = 1
          end,
          ---@type matchup.Config
          opts = {
            treesitter = {
              stopline = 500,
            },
            surround = {
              enabled = 1,
            },
          },
    			},
    		},
    	},
    })
