[sanamiy]

In every content/*.md document Edit this page on GitHub button link is broken.
example: https://pwa.nuxtjs.org/
broken link:
https://github.com/nuxt-community/pwa-module/edit/master/docs/content/en/index.md

FYI, as described in the issue linked above, I confirmed that the link is correct in local environment (i.e. yarn run dev).
So, it seems to be that the documentation site in production environment is not up-to-date for some reasons.

I don't know who is the maintainer of this repository, so let me ping to @Atinux. 🙏

We need to soon upgrade the documentation to Docus V2 or V3. We can keep this issue open in the meantime. (ping @Tahul)
