Setting parquet.thrift.string.size.limit = -1 incorrectly throws

### Describe the bug, including details regarding any error messages, version, and platform.

https://github.com/apache/parquet-java/pull/3359 added a `parquet.thrift.string.size.limit` configuration to allow specifying a custom max Thrift message size. If unspecified or explicitly set to -1, the default (100 MB) is used. The config validation code introduced a minor bug [here](https://github.com/apache/parquet-java/blob/8931c1c55f1fba399dd75139f75bcde0b84137c0/parquet-format-structures/src/main/java/org/apache/parquet/format/Util.java#L420): if the value is explicitly set to -1, `maxMessageSize` is correctly set to the default, but the `configuredMaxMessageSize <= 0` branch will still throw an exception.
