Review Comment:
remove this assertion because in
https://github.com/apache/paimon/blob/74cf00b981917f327fc5bb9d3682ce7bf1d9b62b/paimon-core/src/main/java/org/apache/paimon/operation/DataEvolutionSplitRead.java#L157
we will only create a UnionReader if we have more than one file to read.
However in this scenery, only one column is projected and we only need to read
one File, so the created reader is just a FileReader.
