Expose genesis_config and genesis_records RPC API

[frol]

We have recently added (near/nearcore#2109) new RPC API methods: genesis_config and genesis_records (with EXPERIMENTAL_ prefix).

The API documentation is currently defined in the PR description mentioned above.

Hi @frol . Is this issue still open ?

[frol]

Nope, these methods are already implemented:

near-api-js/src/providers/json-rpc-provider.ts

Lines 201 to 220 in 5c2ea7b

	/**
	* @deprecated
	* Gets the genesis config from RPC
	* @see {@link https://docs.near.org/docs/develop/front-end/rpc#genesis-config}
	*/
	async experimental_genesisConfig(): Promise<NearProtocolConfig> {
	const deprecate = depd('JsonRpcProvider.experimental_protocolConfig()');
	deprecate('use `experimental_protocolConfig({ sync_checkpoint: \'genesis\' })` to fetch the up-to-date or genesis protocol config explicitly');
	return await this.sendJsonRpc('EXPERIMENTAL_protocol_config', { sync_checkpoint: 'genesis' });
	}
	/**
	* Gets the protocol config at a block from RPC
	* @see {@link }
	*
	* @param blockReference specifies the block to get the protocol config for
	*/
	async experimental_protocolConfig(blockReference: BlockReference | { sync_checkpoint: 'genesis' }): Promise<NearProtocolConfig> {
	return await this.sendJsonRpc('EXPERIMENTAL_protocol_config', blockReference);
	}

(well, genesis_records endpoint was removed from the JSON RPC implementation on nearcore side)
