fix: Disable ordinal select item references

[inoorinoor]

Ydb does not support ordinal as item reference. For example query like select * from table order by 1.
It is documented in https://ydb.tech/docs/en/yql/reference/syntax/select/order_by?version=v25.2.

So in this PR I made supportsOrdinalSelectItemReference to return false, to such queries worked in hibernate.

overriden supportsOrdinalSelectItemReference function to return false in YdbDialect, so queries with order by 1 and group by 1 are now working.
