Add Github Actions automatic tests running

[nemothenoone]

We run Github Actions workflow for testing new functionality in many repositories by PR into corresponding repo master. It would be great to run tests also by PR into crypto3 master. We still need to add Github Actions workflow to all the repos apart of the crypto3 itself:

• [ ] crypto3 itself

• [ ] algebra

• [ ] block

• [x] blueprint

• [ ] codec

• [ ] containers

• [ ] ffi

• [ ] hash

• [ ] kdf

• [ ] mac

• [ ] marshalling algebra

• [ ] marshalling containers

• [ ] marshalling core

• [ ] marshalling multiprecision

• [ ] marshalling zk

• [ ] math

• [ ] modes

• [ ] multiprecision

• [ ] passhash

• [ ] pbkdf

• [ ] pkmodes

• [ ] pkpad

• [x] pubkey

• [ ] random

• [ ] stream

• [ ] vdf

• [x] zk
