[SPARK-33045][SQL][FOLLOWUP] Fix build failure with Scala 2.13
### What changes were proposed in this pull request?
Explicitly convert `scala.collection.mutable.Buffer` to `Seq`. In Scala 2.13 `Seq` is an alias of `scala.collection.immutable.Seq` instead of `scala.collection.Seq`.
### Why are the changes needed?
Without the change build with Scala 2.13 fails with the following:
```
[error] /home/runner/work/spark/spark/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/parser/AstBuilder.scala:1417:41: type mismatch;
[error] found : scala.collection.mutable.Buffer[org.apache.spark.unsafe.types.UTF8String]
[error] required: Seq[org.apache.spark.unsafe.types.UTF8String]
[error] case null => LikeAll(e, patterns)
[error] ^
