Dev tools, zkEVM: migrating how-tos

- Consolidate third-party tutorials
- In-house smart contract dev tutorials classified into PoS and zkEVM
- Add zkEVM 'how-to' tutorials to the zkEVM category
- Modify mkdocs.yml to delete 'how-to' section from zkEVM space
- Files continue to live under zkEVM (to avoid 404s)
