Add Section on ZKEmail

From Ayush:

> For context for education, we do have a zk lecture that might be fitting! Specifically it's a one and a half hour onramp from basic set membership proofs all the way up to zkemail (zkiap.aayushg.com)
>
> For uni students, more simple end to end crypto projects will be highest return. We have various project lists at aayushg.com/ideas > crypto (broader crypto ideas) and github.com/zkemail > ideas
>
> Apart from zkiap.com, I've found many students internationallly don't know about basic courses, libgen, or scihub which are all critical
>
> I.e.
> 6.857, applied cryptography, basic blockchains and hashing and zk: https://courses.csail.mit.edu/6.857/2022/handouts (only notes, no videos)
>
> 6.875, advanced theoretical cryptography guiding up to zk and lattices: http://mit6875.org/
