chore: 5795 Upgrade node LTM version

[tihuan]

Reason for Change

• Investigate and upgrade Node from 16.14.2 to latest [SPIKE] #5795
• If the reason for this PR's code changes are not clear in the issue, state value/impact

⚠️⚠️⚠️ ACTION REQUESTED ⚠️⚠️⚠️

1. To run npm run dev properly, you may need to run npm rebuild after this PR is merged into main

Changes

1. Update Node version from 16.14.2 to 20.10.0 (the current LTM)
2. Update its corresponding type file and fix some type issues caused by TypeScript defaulting to NodeJS' API instead of DOM's equivalents, which is what we actually want

Testing steps

1. The whole app should work as intended. Since this is a node related upgrade, it shouldn't affect client side runtime in the browser but mostly server side runtime and build time
2. I've checked server side rendering, app obviously builds for both dev and prod modes, and npm i works for me

WMG rdev BE is currently down, thus e2e tests are failing

All tests should be passing now 💯
