fix(deps): Bump @modelcontextprotocol/server and client to 2.4.0 in node-integration-tests

Resolves the open @modelcontextprotocol/server advisories (high) and the client ones for our direct dependency. @flue/runtime 2.3.0 still pins @modelcontextprotocol/client 2.0.0. Dependabot alert: https://github.com/getsentry/sentry-javascript/security/dependabot/3385
