[TT-1936] Seth with simulated backend

[Tofel]

This PR adds support for passing simulated.Client implementation to Seth, which includes both a client connected to a live RPC and a Simulated Backend.

Below is a summarization created by an LLM (gpt-4-0125-preview). Be mindful of hallucinations and verify accuracy.

Why

These changes introduce support for EIP-1559 transactions, adjust gas price estimation, and include various library updates. The modifications ensure compatibility with recent Ethereum network updates and improve the reliability of transaction processing and gas estimation.

What

• seth.toml: Enabled EIP-1559 dynamic fees for more efficient gas price management on compatible networks.
• seth/tracing.go: Updated RPC dialing to use the MustFirstNetworkURL function, ensuring the connectivity setup is more robust and error-handling is improved.
• go.mod and go.sum: Updated dependencies for better compatibility and security. This includes updates to go-ethereum, which contains critical fixes and improvements for blockchain interactions.
• seth/gas_bump_test.go: Modified gas bumping tests to reflect changes in gas management, particularly for EIP-1559 transactions.
• seth/seth.toml: Adjusted default configurations for gas prices and transaction fees to align with the new EIP-1559 structures and the current network conditions.

Does it replace the ethclient.Client completely? In the dev-platform CLI we're using seth.Client also in the production environment. Our question and request was to be able to swap the real client with a simualted one, so in unit/isolated tests we don't need to interact with Anvil (or similar), but rather in-memory simulated backend.

Here's example how we're constructing seth.Client: https://github.com/smartcontractkit/dev-platform/blob/main/cmd/client/eth_client.go#L94
And here's example how it's used to interact with capabilities registry contract: https://github.com/smartcontractkit/dev-platform/blob/main/cmd/client/capabilities_registry_client.go.

[Tofel]

it doesn't. simulated.Client is just an interface, you can pass *ethclient.Client as simulated.Client. Anyway, this only applies if you pass simulated backed explicitly to the builder like this WithEthClient(backend.Client()).. Otherwise it will use the URL provided and start a normal client.

Ok, thanks for clarification 🙇
