Displaying inline task action warning

[kanej]

With a new Hardhat3 Alpha project, on compile you get inline task warnings:

> pnpm hardhat3 compile
WARNING: Inline task action found in plugin "builtin:solidity" for task "compile". Use file:// URLs in production.
Compiled 1 Solidity file with solc 0.8.24 (evm target: shanghai)

We should suppress those warnings for all the builtin tasks.
