This PR adds a concrete example to the "Schema selection in time travel queries" section in the Spark queries documentation. The example demonstrates how schema selection behaves when: - time traveling by `TIMESTAMP AS OF` and `VERSION AS OF <snapshot_id>` (uses the snapshot's schema) - time traveling by `VERSION AS OF 'branch-name'` and `table.\`branch_<branch-name>\`` (uses the table's current schema) - time traveling by `VERSION AS OF 'tag-name'` and `table.\`tag_<tag-name>\`` (uses the referenced snapshot's schema) The scenario uses a simple `orders` table that evolves its schema (adding a new column) and shows which columns are visible in each kind of time travel query.
