What's the equivalent of require'mason-lspconfig'.setup() for linters?

[gzagatti]

I was installing linters with Mason, but I did not find in the documentation a way to programattically specify them in init.lua.

If I add linters to require'mason-lspconfig'.setup(ensure_installed = {}), I get a message saying that the LSP package is not available.

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

Is it possible to do that? Am I missing something?
