What is the modern Mason configuration?

[NeilGirdhar]

In case it helps others, this seems like a modern Lazy configuration.

-- LSP Configuration
return {
    'mason-org/mason-lspconfig.nvim',
    opts = {
        ensure_installed = { "pyright", "texlab", "ruff", "lua_ls" }
    },
    dependencies = {
        'neovim/nvim-lspconfig',
        dependencies = {
            { 'mason-org/mason.nvim', opts = {} },
            -- Status updates for LSP.
            { 'j-hui/fidget.nvim', opts = {} },
        },
        config = function()
            vim.api.nvim_create_autocmd('LspAttach', {
                group = vim.api.nvim_create_augroup('neil-lsp-attach', { clear = true }),
                callback = function(event)
                    local map = function(keys, func, desc, mode)
                        mode = mode or 'n'
                        vim.keymap.set(mode, keys, func,
                            { buffer = event.buf, noremap = true, desc = desc }
                        )
                    end

                    map("gD", vim.lsp.buf.declaration, "Declaration")
                    map("gd", vim.lsp.buf.definition, "Definition")
                    map("K", vim.lsp.buf.hover, "Hover information")
                    map("gI", vim.lsp.buf.implementation, "Implementation")
                    map("gr", vim.lsp.buf.references, "References")
                    map("<leader>e", vim.diagnostic.open_float, "Show diagnostics")
                    map("<leader>a", vim.lsp.buf.code_action, "Code action")
                    map("<leader>r", vim.lsp.buf.rename, "Rename identifier")
                    map("<leader>F", vim.lsp.buf.format, "Format")
                end,
            })
        end,
    },
}
