proxy cache does not remember pulled tags [REOPEN]

Reopening this issue as it is still reproducible.

Expected behavior and actual behavior: I have several proxies set up. However, Docker Hub proxy does not list tags which I have pulled.

Steps to reproduce the problem:

1. docker pull something via Docker Hub proxy
2. Find this artifact in Harbor UI and see that there are no tags at all
3. API calls like /v2/.../tags/list and /v2.0/.../artifacts/.../tags also return no tags

Versions:

• harbor version: v2.13.1-9384ed0e
• docker engine version: 27.0.3

This seems to be the same issue as originally described here: https://github.com/goharbor/harbor/issues/15591

Could you please reopen and take another look?
