Unmute OldRepositoriesIT

[drempapis]

The mute lumped together two unrelated causes:

1. Painless whitelist boot failure. Nodes died at startup with parser not found for [allocates_dynamic] while loading ML's whitelist.txt, failing cluster orchestration. Fixed by the @allocates_dynamic -> @allocates conversion (Painless: convert x-pack allowlists to @allocates #154206), already on main.

2. RoaringBitmap jar hell. A separate log showed esql-datasource-iceberg jar hell between lib/RoaringBitmap-1.6.15.jar and the module's transitive RoaringBitmap-1.3.0.jar.

fatal exception while booting Elasticsearchjava.lang.IllegalStateException: failed to load plugin esql-datasource-jdbc due to jar hell |

Neither is related to the muted class. I also tried but did not manage to reproduce it locally.

Closes #154229
