docs: add minimal_init.lua

[kylo252]

I saw that this is a common request, so I figured I can create a minimal template in Lua.

@kylo252 Thank you for your cooperation!

I'm not familiar with packer.nvim, but I've seen packer.nvim cause caching issues.
Is there a cache problem with this minimum.lua?

The cache problem is that the plug-in is unintentionally loaded (even though you are not using this configuration file) or the plug-in remains out of date.

I can recommend https://github.com/savq/paq-nvim , very minimal.

I'm not sure, but I don't think there are generally any such issues

I'm not sure what the caching problems specifically relate to, but all I can provide is some general clarification on what people often perceive as caching.

1. Usage of native vim packages - packer (and paq) use native vim packages which were added in vim 8 which means any plugins installed into the start directory which will be the case for anything not conditionally loaded will automatically be loaded by neovim on startup, packer does not control this behaviour

2. The packer compiled file, this is only really relevant for conditionally loading plugins using autocommands or nvim commands and is not really relevant to start plugins. This file is read on startup and registers autocommands etc. to conditionally load plugins

I believe the caching issues are largely due to confusion around the behaviour of vim packages which differs from something like vim-plug which leads users to believe that packer is doing something rather than reverse which is that vim-plug works differently to native behaviour 🤷🏿

From what I can see there is no conditional loading here, so I don't know any reason why there would be any caching related issues

I think the minimal init.lua or init.vim should not be depend on any of plugin mangers.
