feat!: support per network defaults for txn acceptance timeout

[antazoey]

What I did

Allows per network configuration for transaction acceptance timeouts.
Makes the default for local and fork network 20 seconds instead of 2 minutes

How I did it

• Move config logic to ape_ethereum config
• Have property on NetworkAPI to read it and use default when not found

How to verify it

• Create ape project with ape-config.yaml file containing:

ethereum:
  local:
    transaction_acceptance_timeout = 1  # make fail really fast.

Then, try to get a non-existent transaction by first launching a console:

ape console

and then attempting to get a transaction:

txn = networks.provider.get_transaction("0x8f9526ca5ad7c83f4ed91a5d055b1267c0a5d89645307e042e9bbffa8f755391")

(the hash above exists on mainnet but wouldn't in your local environment)
