🔧(y-provider) increase Node.js memory limit

By default, Node.js has a memory limit of
around 512MB, which can lead to out-of-memory
errors when processing large documents.
This commit increases the memory limit to
2GB for the y-provider server, allowing
it to handle larger documents without crashing.
