Describe the Bug

When running Astro with the latest 4.1.11 version of TailwindCSS and @tailwindcss/vite dependancies the following error is reported during build. Reverting back to versions 4.1.10 resolves the issue. I suspect it is due to tailwind adding support for Vite 7.

astro.config.mjs:108:13 - error ts(2322): Type 'Plugin$1[]' is not assignable to type 'PluginOption'.
Type 'Plugin$1[]' is not assignable to type 'PluginOption[]'.

108 plugins: [tailwindcss()],
~~~~~~~~~~~~~

Note, I cannot get StackBlitz to install any dependancies due to an internal npm error. Trying to resolve.

What's the expected result?

Expect build to process normally and not exit with an error
