[Test-Proxy] Create Integration Test Job

The outcome of this issue is a yml job that is added on to the `tools - testproxy` build definition. It should run the `integration` tests for the test-proxy.

This job is eventually going to evolve into the concept of `Update my Recordings` job.

For now, it should verify the following.

- [ ] Test-Proxy can still successfully run through the integration tests currently defined in `tools/asset-sync/assets.Tests.ps1` as they are migrated to the .NET solution.
- [ ] Test-Proxy doesn't break integration with a few of the main repos.
- Run .NET `core`
- Run Python `tables`
- Run JS `utils` + `acr`
