Bug: The formatter cannot be automatically installed via ensure_installed

[luzilong2005]

-- lsp.lua

return {
    "mason-org/mason-lspconfig.nvim",
    dependencies = {
        { "mason-org/mason.nvim", opts = { } },
        "neovim/nvim-lspconfig",
    },
    opts = {
        automatic_enable = true,
        ensure_installed = {
            "stylua"
        }
    },
}

Warning: [mason-lspconfig.nvim] Server "stylua" is not a valid entry in ensure_installed. Make sure to only provide lspconfig server names.

It seems to be an old issue (with solution), see #113 (comment).
