Feature run scripts

[shunsukew]

Resolve https://github.com/AstarNetwork/swanky-cli/issues/144 & https://github.com/AstarNetwork/swanky-cli/issues/134

What were changed

• swanky script run [SCRIPT_NAME] added.
• typedContracts folder moved from tests/typedContracts to typedContract at project root, so that both tests and scripts can use them.
• flipper typedContracts are scaffolded when a project is initialized, so that a sample script 00_deploy.ts can use for showcasing how to deploy contracts by using typedContracts (usually they're generated by swanky contract compile where typechain-polkadot get executed).
• typechain-polkadot >= 1.0.0-beta doesn't need artifacts such as .contract & metadata .json externally. They're embedded in contract-info folder generated by typechain-polkadot command. So, no need for having raw artifacts both in tests and scripts.

Same as swanky contract test, swanky script run also gets version duplication warnings. This PR was for fixing dup warning except testing https://github.com/AstarNetwork/swanky-cli/pull/142.
