This PR fixes a bug where `insertInto()` operations fail with
NumberFormatException when writing to legacy tables that have string partition
values but numeric partition column schemas, even when
`spark.sql.sources.validatePartitionColumns=false` is configured.
### Why are the changes needed?
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.
-->
This is a real issue for users migrating from legacy systems or working with
tables where partition naming conventions don't match the schema. The
validatePartitionColumns=false config exists specifically to handle such cases,
but it wasn't being respected during writes.
### Does this PR introduce _any_ user-facing change?
<!--
Note that it means *any* user-facing change including all aspects such as
new features, bug fixes, or other behavior changes. Documentation-only updates
are not considered user-facing changes.
If yes, please clarify the previous behavior and the change this PR proposes
- provide the console output, description and/or an example to show the
behavior difference if possible.
If possible, please also clarify if this is a user-facing change compared to
the released Spark versions or within the unreleased branches such as master.
If no, write 'No'.

Yes, This PR fixes a bug where users could not write to legacy tables with
mismatched partition types even when
spark.sql.sources.validatePartitionColumns=false was configured.
