[tests] Add support for probes.json (#8279)

Browse Source 
Previously, our test fixtures used to use a probes prop in `vercel.json` that was removed right before it was deployed.

This PR allows a separate `probes.json` file with the same content to separate the test fixture input from the test probes.

This allows us to test real "zero config" deployments without a `vercel.json` file.
