fix: set resolveProvider to false json and yaml server

[akoreman]

Problem

Currently, both the JSON and YAML generic language servers respond with resolveProvider: true in their initialization response. This signals to clients that these language servers support completion item resolve requests, which these servers don't actually support, resulting in errors when clients send resolve requests.

Solution

This updates resolveProvider to false to accurately describe the capabilities of these language servers.
