This is derived from WT-14937.

test_rollback_to_stable01 is currently globally disabled. By simply enable this (applying following diff), the behaviour is different from DSC to ASC mode.

• ASC: I've started a patch with unit test in non-disagg variants, all unit test passed, which means this is still a valid test now.
• DSC: By removing the skip, the test was still be skipped by inmem and rollback_to_stable in the test suite disagg filters here.
  • This is a name based filter, so skip this test in disagg test seems work as expected, need double confirm.
