Downgrade NumPy used by HRNet (cvat-ai#5574)

HRNet uses `np.int` which throws an error for NumPy >= 1.24, because its
deprecation was finally expired. This PR creates an additional step
during HRNet function image build, downgrading NumPy for a version <
1.24.

### Motivation and context
Closes cvat-ai#5571.
