## Description
this makes the extra luasnip lazy load at the same time as nvim cmp.
just putting `lazy = true` works because `nvim-cmp` when being loaded
with `InsertEnter` also load `cmp-luasnip`, which itself load `LUASNIP`.
you can see the problem in the following discussion
https://github.com/LazyVim/LazyVim/discussions/3966 where luasnip was
not lazy loaded when starting lazyvim. This was also loading nvim-cmp
and all its dep when starting lazyvim, which negatively impacted
performance.
