Outdated Tailwind CSS startup command

[christeefy]

Hi there,

Using dx new ... to set up a new project generates a README containing the following Tailwind code snippet. However, executing the command produces an error:

>>> npx tailwindcss -i ./tailwind.css -o ./assets/tailwind.css --watch
npm error could not determine executable to run

According to the Tailwind CSS doc linked in the README, the command to run when adapted for Dioxus template projects, should instead be:

npx @tailwindcss/cli -i ./tailwind.css -o ./assets/tailwind.css --watch

which indeed works.

I believe the previous command was for tailwindcss@v3.x.

I'm relatively new to frontend, so apologies in advance if my conclusions here are incorrect.

Otherwise, I'm happy to open a PR to make the updated changes to the templates.

Also, should the templated tailwind.config.js be removed as well? From my understanding that is also a V3 thing.
