feat(ci): use corepack when setting up node in CI

[jordanshatford]

Describe the problem

Current CI uses PNPM action to setup the version of PNPM

Describe the proposed solution

Instead we should setup Node with corepack to use the package manager specified in our package.json. This will also ensure the expected version is installed.
