feat(vatsal): Create new config vatsal

kickstart folder contains the original init.lua file. Current init.lua
gets it's config from lua.vatsal.plugins which what I created to
modularize the code and enable lazy loading.

Init to lua now loads all the plugins from vatsal.plugins

lua/vatsal/plugins/nvim-tree.lua
