chore: upgrade fuel-core to 0.18.1, forc to 0.40.1

[Dhaiwat10]

Summary

This PR bumps the fuel-core version to 0.18.1, and forc to 0.40.1. I have used FuelLabs/fuels-rs#950 and https://github.com/FuelLabs/fuel-core/releases/tag/v0.18.0 as references.

Major changes

• The resourcesToSpend API has been reverted back to coinsToSpend.
• Signing a transaction now requires chainId.
• The produceBlocks API has been updated.
• Message outputs have been removed. We don't need to specify them in the outputs anymore.
• The MessageProof schema has been updated according to the new proof API.
• Update some contracts according to the new Storage API
• Use the Sway version from this unreleased PR: Upgrade to fuel-core 0.18.1 and fuels-rs 0.41 sway#4525

Closes #976

FYI - we'll need to use the sway version that's compatible with fuel-core 0.18, which is currently unreleased in a PR here: FuelLabs/sway#4525
