Upgrade Ethers.JS version used by view-function EAs

[alecgard]

• Upgrade the version of ethers.js used by the view-function EA's to v6.13.2

• This so that we can use the fix introduced in v6.11.0, to allow the use of the override keyword in provided ABIs: https://github.com/ethers-io/ethers.js/releases/tag/v6.11.0

  Allow override keyword in human-readable ABI and improve error messages (EE Error: unexpected tokens: <TokenString ID:override KEYWORD:returns OPEN_PAREN... ethers-io/ethers.js#4514, ethers Interface throws EE Error: expected ID; error ethers-io/ethers.js#4548; be5ec2d).

• This should stop the view-function EA's from log-spamming unknown modifier: override when fetching data for an ABI which includes the override keyword

Testing

• Tested with the below query, that incudes the override keyword in the function signature

curl --location 'localhost:8080' \ --header 'Content-Type: application/json' \ --data '{ "data": { "address": "0x9ba021b0a9b958b5e75ce9f6dff97c7ee52cb3e6", "function": "function previewRedeem(uint256 shares) public view override returns (uint256)", "inputParams": [ "1000000000000000000" ], "network": "ETHEREUM" } }''

• Before the fix, the EA would spam unknown modifier: override every time it fetched data. Post-fix, log spam is gone and EA continues to serve data.
• Had to update the fixtures in our integration tests, as the upgraded ethers.js defaults to using JSON-RPC batch requests
