fix(pnpm): inject rxjs path into any-observable

[aleclarson]

When installing listr with pnpm, an issue occurs where any-observable cannot find any Observable implementation. Since listr already depends on rxjs, we can just inject it before importing any-observable.

Might need a try..catch in here. 🤔

This seems to also break the usage of lint-staged when using yarn v2. Is there any chance that you can put some eyes on this, @SamVerschueren?
