Updating github runner from 20.04 ahead of deprecation (#1223)

## 🎟️ Tracking

actions/runner-images#11101

## 📔 Objective

The ubuntu-20.04 runner will be removed from GitHub on April 1st. This
PR updates the ubuntu version to 22.04

The pinned version of actions/cache was a version behind what we're
using everywhere else and has been deprecated by Github, so that's been
updated to resolve one of the tests that was failing.
