Swap the order of Ax and BoTorch installation in tutorials workflow (#1483)

Summary:
Without this, Ax installation step would install BoTorch from PyPI, which would ignore the `ALLOW_LATEST_GPYTORCH_LINOP` env var.

Pull Request resolved: #1483

Test Plan:
Imported from GitHub, without a `Test Plan:` line.
