fix: add --ignore-scripts to npm ci in github action

I think we were reliant on buggy behaviour in npm@7 where `npm ci`
wasn't running some of the lifecycle hooks:
npm/cli#1905 (comment)

This got fixed in npm@8 but now our CI process breaks:
npm/cli@d825e90

Decided to follow the recommendations from husky's docs to do this so it
doesnt run the `prepare` step:

```sh
npm ci --ignore-scripts
```
