upgrade web3.js

### Description

In order to take advantage of the London fork, we need to upgrade web3.js to the latest version (1.5.1).

Release notes can be found here: https://github.com/ChainSafe/web3.js/releases?after=v1.0.0-beta.42

It doesn't look like there have been a huge amount of breaking changes, but we need to be sure to check what has changed on the minor/patch and update everything accordingly. The main change that we need to encompass is with regards to gasPrice (we need to switch to using maxFeePerGas and maxPriorityFeePerGas) or omit any mention from the tx's.

Upgrades will need to be made against any script that utilises web3.js:
