Release Blocker: Stop skipping the cached sync tests in CI

[teor2345]

Motivation

PR #2314 changed the name of the cached state test functions in the code, but didn't change the test names in the CI workflow. This disabled the cached sync tests since Zebra 1.0.0-alpha.11.

Solution

• Make sure Zebra's CI workflows are using the correct names for the cached state tests
  • using fastmod sync_past_canopy sync_past_mandatory_checkpoint .github zebra*
  • double-check rg sync_past_canopy .github zebra*

This PR re-enables the tests that should have caught bug #2401, so it might fail on main until PR #2404 is merged.

Review
