Export tailwind config file

[tobiasdiez]

Is your feature request related to a problem? Please describe.

As outlined at https://tailwindcss.nuxtjs.org/tailwind/editor-support, the vscode tailwind extension has some limitations around the config file. In particular, it does not work if the config is provided in nuxt.config.ts.

Describe the solution you'd like

Write a dummy config file with the merged config to .nuxt/tailwind.config.cjs, which then can be used with the vscode extension via tailwindCSS.experimental.configFile.

Describe alternatives you've considered

Use a tailwind.config.cjs file instead of specifying the config in nuxt.config.ts.
