eth.getBlock with hydrated = true returning empty transaction objects

[nikoulai]

Description

Solution for #5470

eth.getBlock was returning an empty object for block.transactions.

The error was in

web3.js/packages/web3-utils/src/formatter.ts

Line 158 in bfce27f

const schemaProp = findSchemaByDataPath(schema, dataPath);

inside findSchemaByDataPath, which doesn't handle the oneOf type ( and couldn't since no info is passed in order to choose the right one.)

My proposed solution is to save the options of oneOf and pass them to findSchemaByDataPath.

This was my testcase

                        const web3 = new Web3Eth(
				'https://mainnet.infura.io/v3/6120b2e72c304b4eadafe2bf33862ac4',
			);
			const blocks = await web3.getBlock(15602045, true);
			console.log(blocks.transactions);

In existing integration test , there should be additional check of transactions list present in case of hydrated true. or we can add a new test for querying a block with txs on some existing testnet.
