The tests snapshot_read_at_cluster_time_crud_operations.js and snapshot_read_at_cluster_time_ddl_operations.js were excluded from running in transaction concurrency suites via the does_not_support_causal_consistency tag. However SERVER-95023 is removing that tag from being part of the exclude set in multi_stmt_txn concurrency suite, since that tag doesn't actually apply to the txn suites.

After removing the does_not_support_causal_consistency from the above two tests, I ran them in the txn concurrency suites and they failed, although the failure on snapshot_read_at_cluster_time_ddl_operations.js seems easy to fix and test-only. The other fix seems harder - we might have to change some shell javascript code. See comments for patch link.

I've kept these two tests disabled in the txn suites by adding the does_not_support_transactions which is more appropriate. I have not tagged the tests with a TODO on this ticket number because I think there's a decent chance we don't bother re-enabling these two tests.

Please wait until SERVER-95023 goes in before starting this work.
