[IPFS] Secure context for `ipfs:`-Scheme

Similar to https://github.com/brave/brave-browser/issues/13706 which is about the ipns: scheme, the ipfs: scheme is currently not considered ‘safe’ by the browser:

This is not true.

Brave should give the user information about what exactly is safe in this context via the context menu, and show that this content is indeed secure when using the build-in ipfs node.

Brave version (brave://version info)

This is “only” a cosmetic issue 😃 cc @autonome @bbondy @jessicaschilling

• 💚 ipfs:// is marked as Secure Context, you can test by opening console and reading the window.isSecureContext flag
• 💔 the error on your screenshot comes from the UI related to security model based TLS certs from HTTPS (which we don’t use in IPFS) – I agree, this is confusing, we should improve this popup on ipfs:// pages
  • MVP fix could be replacing popup body with info that content was loaded from IPFS node managed by brave and “Learn more” would openbrave://ipfs
