Integration test cleanup workflow (#138)

## Problem

Integration tests attempt to cleanup after themselves with `afterEach`,
but it is possible for the `afterEach` delete to fail or for someone to
add a test that does not have proper cleanup steps. If we don't have a
way to cleanup these orphaned resources, eventually all tests will fail
due to quota exhaustion.

For example, while trying to write tests for create collection I
accidentally created a bunch of these abandoned resources because the
afterEach call to deleteCollection was failing; collections can't be
deleted while they are still being created.

## Solution

Create a workflow that deletes all indexes and projects within the
sdk-node-testing project.
- Can be triggered manually
- Runs automatically once per day

## Type of Change

- [x] Infrastructure change (CI configs, etc)
