in the case of tailwindcss, even tho the cli has that name, the package is actually @tailwindcss/cli so running npx tailwindcss doesn't make sense. the proposal is to add an special case where it actually runs npx --no-install @tailwindcss/cli <args> whenever we call exec.Npx. this will allow to use tailwindcss without any prior setup (apart from having npx)

the objective of this change is to avoid needing to install tailwindcss cli globally, nor having a npm/js project setup under hugo (defeats the purpose of the standalone tailwindcss cli)

change should be in this function

particulary adding a new exception here

I am open to do the PR after the heads up
