Update webpki and ring-xous dependency

[Kailai-Wang]

Pretty much a copy-up of litentry/litentry-parachain#2229, with additional adjustments of error types and scale-info crate update.

If we need to use the pallets in no-std, we need to override the ring crate, like here:

[patch.crates-io]
ring = { git = "https://github.com/betrusted-io/ring-xous", branch = "0.16.20-cleanup" }

Thanks, I updated it. It should be ready for review now.

Nice, looks good, except for one fundamental question, I have only one comment. Otherwise, I like the change, it makes the code more readable, and I also like that we can get rid of our fork.

You only need to fix the toml-fmt, and I would like to ask you to mention the patch in the readme. Thanks a lot for the contribution!

Thanks, I fixed that!
If you are happy with the text/position in README, please feel free to adjust it

Nice, looks good to me!

this causes trouble when I try to integrate it, even with the suggested patch:

smells like some missing std feature flag propagation

copying the Cargo.lock file from litentry fixed the mentioned issue
