Faucet for aleph-node chain

This repo is a fork of https://github.com/paritytech/polkadot-testnet-faucet, yet it is now its own being:

• it has the same codebase as the upstream repo when it comes to basic functionality (sending tokens), although that codebase is pretty old (from 2019)
• it does not have matrix functionality
• it has AlephZero own branding
• It is used only on Devnet and Tesnet environments.
