Re-sourcing warning in Lazy when attempting to use automatic server setup with mason

[armanschwarz]

I'm trying to use lazy to install and setup lspconfig, mason and mason-lspconfig with automatic server setup. My attempt at adapting the instructions at h: mason-lspconfig-automatic-server-setup to lazy looks like this:

    {
        'williamboman/mason.nvim',
        config = function() require('mason').setup() end,
        version = 'v1.8.0',
    },
    {
        'neovim/nvim-lspconfig',
        dependencies = { 'williamboman/mason.nvim' },
        commit = 'eb1b53162755888ff75e495797071644d983bff7',
        config = function()
            vim.cmd [[autocmd BufWritePre * lua vim.lsp.buf.format()]]
        end
    },
    {
        'williamboman/mason-lspconfig.nvim',
        dependencies = { 'williamboman/mason.nvim', 'neovim/nvim-lspconfig' },
        version = 'v1.17.1',
        config = function()
            local config = require('mason-lspconfig')

            config.setup({
                ensure_installed = { 'lua_ls@3.7.0', 'pylsp@1.8.0' }
            })

            config.setup_handlers({ function(server_name)
                require('lspconfig')[server_name].setup({})
            end
            })
        end
    },

When I load neovim, it seems to actually work, but when I look at :messages I see Re-sourcing your config is not supported with lazy.nvim

I think this is an issue with the fact that inside setup_handlers I'm requiring lspconfig, which is a dependency/other module, but I don't know how else I'm supposed to do this.
