Fetch registry keys for attestations/provenance assertion #179
Description
We need to implement the https://registry.npmjs.org/-/npm/v1/keys endpoint because we need the registry keys to implement verification of a given package provenance/attestation with pacote
The goal of the task is to add a new API here: https://github.com/NodeSecure/npm-registry-sdk/tree/main/src/api
- TypeScript interface for the response
- With documentation (README)
- Tests
