[SPARK-45423][SQL] Lower `ParquetWriteSupport` log level to debug
### What changes were proposed in this pull request?
This PR aims to lower `ParquetWriteSupport` log level from INFO to DEBUG
### Why are the changes needed?
Currently, `ParquetWriteSupport` is too verbose at INFO level because it
dumps the Parquet file schema per file. Since this is the only log in
`ParquetWriteSupport`, the users can see this via a proper `log4j2.properties`
setting when they want to debug jobs.
```

23/10/05 16:29:43 INFO ParquetWriteSupport: Initialized Parquet
WriteSupport with Catalyst schema:
{
"type" : "struct",
"fields" : [ {
"name" : "id",
"type" : "long",
"nullable" : false,

} ]
}
and corresponding Parquet message type:
message spark_schema {
required int64 id;
}
23/10/05 16:29:43 INFO MagicCommitTracker: ...
```
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Manual tests.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #43230 from dongjoon-hyun/SPARK-45423.
