I am not so sure if we want to maintain translations for docs, given the fact that:

• We duplicate the sources of truth. Every time we update something, we need to spend extra effort updating translations or we create misalignment
• ofetch is not a very user-facing library I suppose?
• AI nowadays could provide very accurate translations already

Thanks for PR dear @AllenYu0118 and willing to help on translations. I think @antfu is correct as keeping the docs up to date can be challenging in the future. We might think of automated translations in website in the future. I have moved the follow to this thread: unjs/website#207
