Resolving Env which is set by vm.setEnv

[wiasliaw]

Component

Forge

Describe the feature you would like

In config reference, rpc_endpoints is enable to take environment variable, like mainnet = "${RPC_MAINNET}".

However, it only available when env is exist or provide in command, i.e. RPC_MAINNET=https://... forge ..... It cannot take env which is set by cheatcode setEnv.

Use case is that: Read Alchemy API key through vm.setEnv and resolve in config for multiple fork.

[rpc_endpoints]
optimism = "https://optimism.alchemyapi.io/v2/${ALCHEMY_KEY}"
goerli = "https://eth-goerli.g.alchemy.com/v2/${ALCHEMY_KEY}"

I see, yeah, so basically what happens is that we try to resolve all of them when the test are started, I guess in this scenario we simply should try again when it is requested
