📚 Description

Nuxt I18n is running into issues specifically with yaml files since nitro 2.9.2+, I think because we're trying to parse and transform the file ourselves but it's already been handled as a raw file?

Let me know if this is not the correct way to resolve this or if there is a way for us to exclude specific files from being handled, I'm following this PR https://github.com/unjs/nitro/pull/2239 as an example (it looks like it added checks for yaml as well anyway).

Would you please make a minimal reproduction with nitro that works before 2.9 and broken with 2.9.2? 🙏🏼 (i understand it might be a bug. it needs reproduction to proceeded)

Sorry, I should have included a reproduction in the first place, I know how annoying it can be without (was a bit drained).

Here is the reproduction: https://github.com/BobbieGoede/nuxt-i18n-yaml-nitro-raw

Interesting to note, this issue only happens when using the server side translation feature, which adds a server/nitro plugin as well as plugins to transform yaml and json5 files (see relevant code), there are no issues using json5 files as seen in the reproduction.

Using nitro 2.9.1

• Install and run using pnpm i && pnpm run dev
• Open page and observe behaviour is as expected
• (optional) Build project using pnpm run build
  • Observe transformed yaml locale file at .output/server/chunks/build/ja-[hash].mjs

Using nitro >=2.9.2

• Remove pnpm.overrides from package.json and install and run again using pnpm i && pnpm run dev
• Terminal will throw error [worker reload] [worker init] _import_meta_url_ is not defined, page stuck on Nuxt loading splash logging 503 status
• (optional) Build project using pnpm run build
  • Observe transformed yaml locale file at .output/server/chunks/raw/ja.mjs

Just adding on that this seems to be throwing an error in my projects as well. They use the rollup yaml plugin to process the yaml files into JS objects, but after nitro 2.9.2, there's an error on dev startup saying no such file or directory. There's probably a way for me to make sure the raw plugin doesn't take over that may resolve the issue, but I assume this PR will do that too.
