Include null-ls as alternative for Snippets support

null-ls

Requested feature

Currently, lspconfig suggest either cmp or coq for snippets support, but both these options are hard to configure (compared to lspconfig) and include a lot more (maybe unwanted) features, including:

• override completion feature and mapping, forbidding the use of omnifunc
• include other sources, like ctags

As an alternative, null-ls can be used for extra completions, and supports luasnip or vssnip as sources for snippets (https://github.com/jose-elias-alvarez/null-ls.nvim/blob/main/doc/BUILTINS.md#completion) with a far easier setup.

For people who wants to dive into the native lsp support without huge plugins, null-ls seems a better alternative. I've tried cmp and coq and found both too intrusive for my simple nvim setup.

No PR for the wiki, so I just included in https://github.com/neovim/nvim-lspconfig/wiki/Snippets#null-ls--luasnip
