Logger doesn't work anymore

From the graphql-language-service-server package (at least, could be shared further).

It used to work before the TS rewrite but now logger emits nothing when connected to say VSCode extension now.

process.stderr.write seems to work though.

@divyenduz and I had a session and tried to track down what changed in graphql-languagesrver and client from 3.5.1. My guess is that the language server no longer writes to stderr as it did before, and somewhere in vscode-jsonrpc this changed over major versions. we decided manually writing to stderr in the Logger._log() will fix it for now, but it would be great to know why this regression occurred

This one seems to work because in graphql-language-service-* it is a process.stderr.write

process.stderr.write(`Definition not found for GraphQL type ${name}`);

Want to pair on this real quick?

In 10-20 minutes maybe?
