chore: 🤖 Add strict .npmrc file (#561)

* chore: 🤖 Add strict `.npmrc` file

Add `.npmrc` with sane defaults

* Update package.json

* feat(ci/cd): Add GitHub Action for auto-assigning PRs

out of the recipes from https://github.com/actions-ecosystem/recipes this sounded very interesting. As we're sometimes forgetting to set ourselves as the assignee after opening a PR, this action would be very helpful.

* Delete .github/workflows/auto-assign.yml
