Updating RPC error schema

[jakmeier]

Description

With the upcoming release of stateless validation in Near Protocol, there are new errors a RPC node may return when a transaction is submitted. Notably, ShardCongested, ShardStuck, and ReceiptSizeExceeded. These are about to land on testnet this week and will make it into mainnet, hopefully within 5-6 weeks.

I wanted to updated the error schema to include them. But I don't get how exactly this should work. Especially how to update packages/near-api-js/src/generated/rpc_error_schema.json.

In the main Readme, there is this description:

### Update error schema

Follow next steps:

1. [Change hash for the commit with errors in the nearcore](https://github.com/near/near-api-js/blob/master/packages/utils/fetch_error_schema.js#L8-L9)
2. Fetch new schema: `node fetch_error_schema.js`
3. `pnpm build` to update `lib/**.js` files

Step 1 seems outdated, since the linked line already points to master instead of a specific commit. Also, the path has changed. (I can send a fix PR but first need to understand what the correct process is)
Step 2 works and updates the file in packages/utils/src/errors/rpc_error_schema.json as expected with the new error variants.
Step 3 succeeds but doesn't update anything for me.

After these steps, I have an updated packages/utils/src/errors/rpc_error_schema.json but my packages/near-api-js/src/generated/rpc_error_schema.json file still contains the old schema without new errors. Since this is in the generated folder, I assume there must be a script that updates it. But it looks to me like this is a different format, perhaps just an old format.

Can someone help me figure out how to update the error schema fully, including packages/near-api-js/src/generated/rpc_error_schema.json?

I'm gonna take another stab at figuring this out. Any inputs regarding the generated files would still be appreciated.

My best effort attempt at this:

• feat: update RPC error schema for protocol version 69 #1363 for the schema update
• docs: update RPC error schema update process #1364 fir the fixed documentation
