fix(module): Nuxt 2 support

[Tahul]

Since 5.2.0, some Nuxt 2 users encountered issues with the module.

@bmulholland kindly found it was related to @nuxt/kit inconsistencies between Nuxt 2 and 3.

That PR solves the support for tailwind.config in Nuxt 2, and disables the config viewer in that environment.

Config viewer seem to break the stack as @nuxt/kit addServerHandler seem to break the module in that environment.

That issue is tracked here, thanks to @harlan-zw: #507

Resolves: #500

Thanks for the fix <3

Hey @bmulholland ;

If you want to use the fix in your app, I made an edge publish for it:
@nuxtjs/tailwindcss-edge@5.3.0-a9077c2

Thanks for your collaboration and sorry for not checking Nuxt 2 support earlier, it was unexpected!

[bmulholland]

Hah! I bet it was unexpected :). A bug in a core nuxt library caused by an ambiguous, undocumented configuration parameter that changed between versions also by the core library is one hell of a gotcha.

[harlan-zw]

Looks good 👍 The Nuxt 2 playground will be useful to avoid regressions in the future

Would love to see this merged soon ❤️

Not sure if this is related, but I am also getting this error when I tried to add it as a module inside my builder class but for my case it seems like downgrading didn't fix this issue

#505

nuxt/nuxt#10247

Further investigation shows that nuxt-highlightjs somehow add the css array an object instead of a string, and that cause the resolvePath function to fail, not sure if this is a error from the tailwindcss side, or is it an error in nuxt-highlightjs side.
