test: un-ignore exec_azure_query_capacity, now passing (#636)

## Summary
- Un-ignore `exec_azure_query_capacity` test — the pipefail bug has been
fixed and the test passes
- `exec_vercel_deploy` remains ignored (still fails with exit code 2)

## Test plan
- [x] `exec_azure_query_capacity` passes with `--ignored` flag
- [x] Full test suite passes
