fix: resolve dependency and type conflicts

[chungjac]

Problem

dependency issues

Solution

1. In this PR: feat: Adding ATX-FES apis support for transformation #2521, the @aws/language-server-runtimes package was changed from using exact version 0.3.6 to ^0.3.8 which allows minor updates. However in app/aws-lsp-partiql-runtimes/package.json, this was updated to 0.3.8 instead of ^0.3.8. Updating it to ^0.3.8 to fix the nested node_modules type conflict issue (pinned version was causing npm to install a separate copy)
2. Received errors for node-fetch since this is no longer in the dependency tree. We can remove the import type { RequestInit } from 'node-fetch' as we can now use the native fetch which is built into Node 18+
3. Updated package-lock.json

Testing

npm run clean
npm install
npm run compile
