Tailwindcss v4 Release breaking changes

Unfortunately the Tailwindcss v4 Release broke our existing non node.js Tailwind Web Project Templates which used npx tailwindcss to generate the tailwind app.css.

This should be changed to use npx tailwindcss@v3 in your App’s package.json, e.g:

{
    "scripts": {
        "ui:dev": "npx tailwindcss@v3 -i ./tailwind.input.css -o ./wwwroot/css/app.css --watch",
        "ui:build": "npx tailwindcss@v3 -i ./tailwind.input.css -o ./wwwroot/css/app.css --minify",
    }
}

All existing non-node.js Tailwind Templates now include this change.
