nvim: Switch to external luarocks dependency

Using external luarocks instead of a luarocks plugin for now. The amount
of dependencies to install is not smaller the other way now (having to
install libreadline-devel) so this should be fine.

I have captured more info in daily log 2025-03-11 on my reasoning.
Suffice it to say: both lazy.nvim 'hererocks' installation, this
external luarocks dep and the luarocks.nvim plugin are brittle in their
own ways. 

For now, I have settled on the external dependency as it remains the
simplest way to achieve what I want (image.nvim) pictures. Though it
requires quite a few dependencies overall:

`xbps-install lua51 lua51-devel luarocks-lua51 ImageMagick libmagick-devel`
