Feature: Any plan for source code adaptation with Lua 5.4.x

### Issues - [x] I have checked [existing issues](https://github.com/rest-nvim/rest.nvim/issues?q=is%3Aissue) and there are no existing ones with the same request. ### Feature description Hi everyone, I tried to install this extension with LazyVim latest. But always ended up with failed as the installation requires Lua 5.1. I'm wondering if there is a plan to implement or fixing the code to make it adapt with the latest Lua version 5.4.x? Thanks a heap Kind regards,
