This PR is a follow up to #15193 for Session-Level time travel in Spark.
The previous PR works for Spark 4.0 and below since Iceberg still performs snapshot selection at scan time. But, in the new DSV2 that is not possible anymore, therefore, I am proposing a Spark extension that post-planning replaces DSV2 with the correct timestamp if there is one set in the spark conf, this allows us to still have this very useful time-travel conf.
This rule, follows the same pattern as ResolveBranch which is another poshoc rule created due to the same changes in DSV2
