doc: sea.getRawAsset(key) always returns an ArrayBuffer

[ShenHongFei]

sea.getRawAsset(key) always returns ArrayBuffer, not string. The return type in the documentation is wrong.

node/src/node_sea.cc

Line 600 in bd3c25c

Local<ArrayBuffer> ab = ArrayBuffer::New(args.GetIsolate(), std::move(store));

node/lib/sea.js

Lines 15 to 35 in bd3c25c

	/**
	* Look for the asset in the injected SEA blob using the key. If
	* no matching asset is found an error is thrown. The returned
	* ArrayBuffer should not be mutated or otherwise the process
	* can crash due to access violation.
	* @param {string} key
	* @returns {ArrayBuffer}
	*/
	function getRawAsset(key) {
	validateString(key, 'key');
	if (!isSea()) {
	throw new ERR_NOT_IN_SINGLE_EXECUTABLE_APPLICATION();
	}
	const asset = getAssetInternal(key);
	if (asset === undefined) {
	throw new ERR_SINGLE_EXECUTABLE_APPLICATION_ASSET_NOT_FOUND(key);
	}
	return asset;
	}
