Update node modules

[calumy]

This PR updates the package-lock.json file to version 2 as this was highlighted during the "Install npm dependencies" stage of a CI run. This should speed up CI runs when the cache is not available, for example when running using the workflow_dispatch trigger, as the new lock file will not need to be generate before the installation begins.

Typescript was also added to node_modules as it a requirement for a requirement for eslint-plugin-jest. As this is a dev dependency, I'm not sure if it should be included in the repo. Please let me know if you would like this PR to be updated to remove it (and the other dev dependencies).

Hi @CalumY, thanks for the contribution. You're right, the update to lockfile v2 is overdue however, I'll push it myself for security reasons as I cannot review that many changes.

Regarding typescript, I want to avoid including it in the dependencies for as long as possible because we don't need it in the current toolchain and I don't want the extra burden of updating ts versions.
