fix: minor fixes based on intermittent test failures (#3465)

Browse Source 
1. preload busybox image to fix: https://github.com/project-zot/zot/actions/runs/18614431126/job/53077015870?pr=3465
2. stabilize test coverage in by using different error type: https://app.codecov.io/gh/project-zot/zot/pull/3444/indirect-changes
3. attempt to fx an intermitent sync test failure:
Failures:

  * /home/andaaron/zot/pkg/extensions/sync/sync_test.go
  Line 4857:
  Expected: digest.Digest("sha256:dc1377539a9db8bf077100bfa3118052feb6b5c67509ca09bdd841e4ac14c4cc")
  Actual:   digest.Digest("sha256:3a3fb31a422846a680f0a07b8b666bdcb1122d912d1adca79523c7bf2715996e")
  (Should equal)!

4. fix a race condition in sync by, I don't have a link, but this is the failure:

  * zotregistry.dev/zot/pkg/extensions/sync/sync_test.go
  Line 5963:
  Expected: 1
  Actual:   2
  (Should equal)!
