URL: https://github.com/apache/beam/issues/26870
### What happened?
On 2.48.0-SNAPSHOT, reading from a BigQuery table with a column of type
`ARRAY<STRING NOT NULL> NOT NULL` causes the following exception:
```
org.apache.beam.sdk.Pipeline$PipelineExecutionException:
java.lang.ClassCastException: class java.lang.String cannot be cast to class
java.util.Map (java.lang.String and java.util.Map are in module java.base of

```
Looking at `BigQueryUtils.java:697`, it looks like `toBeamValue` expects a
List to have inner type `Map<String, Object>`, when the passed in value is
`List<String>`.
