home: vim: lspconfig: use native configuration

The `nvim-lspconfig` "framework" is being deprecated to use the native
`vim.lsp.config` and `vim.lsp.enable` functionality.

I _could_ remove the `is_executable` checks, as native LSP handling does
_not_ loudly error out when enabling a server which isn't executable.
However I think `:LspInfo` is more readable if I don't.
