Add transaction hash field (txHash) to each item in RPC's getEvents response

[Shaptic]

See stellar/js-stellar-sdk#938 and the actual proof here:

curl -s --location 'https://soroban-testnet.stellar.org/' \
  --header 'Content-Type: application/json' \
  --data '{
    "jsonrpc": "2.0",
    "id": 10235,
    "method": "getEvents", "params": {"startLedger": 1184000, "endLedger": 1185072, "filters": [{"topics": []}]}
}' | jq '.result.events[0]'

returns the following:

{
  "type": "diagnostic",
  "ledger": 1184016,
  "ledgerClosedAt": "2024-04-18T18:05:21Z",
  "contractId": "",
  "id": "0005085309997948928-0000000000",
  "pagingToken": "0005085309997948928-0000000000",
  "topic": [

  ],
  "value": "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",

}

as you can see, there is an undocumented txHash field.

@Shaptic Will you run yarn rpcspec:build to generate a new openrpc.json file in the PR?

Edit: I don't know much about git hooks, but if anybody knows how we can "force" any commits with changes to the /openrpc/src/* files to run that yarn command, that would be super awesome!

@ElliotFriend guess I fail at avoiding running yarn in the stellar-docs repo hehe 🙃 fixed!

@Shaptic I pushed a commit with updated examples. I also noticed the returned value field is no longer an object, but is a string now. So, I updated that as well while I was working in the vicinity (although there are other updates/changes to the spec that are likely needed anyway, see #467).

As soon as it builds/previews, I'll be happy to approve/merge. Thanks for the help keeping things updated!!
