Checklist

• I have searched for similar issues.
• For Python issues, I have tested with the latest development wheel.
• I have checked the release documentation and the latest documentation (for master branch).

Steps to reproduce the issue

Pip (version 22.0.3) can't find the 0.15.1 version even though it's on pypi:

pip install open3d==0.15.1 
ERROR: Could not find a version that satisfies the requirement open3d==0.15.1 (from versions: 0.10.0.0, 0.11.0, 0.11.1, 0.11.2, 0.12.0, 0.13.0, 0.14.1)
ERROR: No matching distribution found for open3d==0.15.1

The wheel on the installation page (https://storage.googleapis.com/open3d-releases-master/python-wheels/open3d-0.15.1-cp38-cp38-manylinux_2_27_x86_64.whl) works fine as a workaround.
