## What is this PR for?
A small contribution to enhance the documentation and make it easier to
use.
While vim-dadbod and vim-dadbod-ui recommend using dotenv.vim for env
file injection, we aim to provide a simpler method. Instead of
implementing file parsing or relying on an external plugin (dotenv.vim),
just try directly using a Lua table.
