Description

This issue is to track using of CI caches to speed up CI workflows.

To enable caching for NPM-based projects:

- Add the `cache: npm` input to instances of the `actions/setup-node` Github Action:
```
using: actions/setup-node@v4.0.0
with:
cache: npm
```
- Add `--prefer-offline` to instances of `npm ci`
This will stop NPM from performing "staleness" checks, without the "hard failure" of `--offline`.

## Restrictions

The storage of cache is 10 GB per-repository, with a maximum "no access" duration of 7 days. If any of these limits are hit, they will be automatically evicted. Hence, there should not be much additional maintenance oerhead for us.
