Update lazydev config to fix "Undefined field fs_stat" LSP error (nvim-lua#1040)

7513ec8 switched from neodev to
lazydev, but in the process it introduced an LSP error in `init.lua`,
which degrades the desired "first timer" experience of kickstart.nvim.

This commit follows the configuration suggested in
https://github.com/folke/lazydev.nvim/tree/6184ebbbc8045d70077659b7d30c705a588dc62f#-installation
which resolves the LSP error.
