URL: https://github.com/apache/spark/pull/52837
### What changes were proposed in this pull request?
Incorrect parameter **error** is used for CANNOT_PARSE_DATATYPE error class
in PySpark code. It expects **msg**. Due to this the error produced during
usage is incorrect:
Example:
```
StructField.fromJson({"name": "col1", "type": "NewType", "nullable": "True",
"metadata": None})
```
Error:
```
assert set(message_parameters_from_template) == set(message_parameters), (
AssertionError: Undefined error message parameter for error class:
CANNOT_PARSE_DATATYPE. Parameters: {'error': 'NewType'}
```
### Why are the changes needed?
Bug fix
### Does this PR introduce _any_ user-facing change?
Yes, now correct error would be printed into console:
```
raise PySparkValueError(
pyspark.errors.exceptions.base.PySparkValueError: [CANNOT_PARSE_DATATYPE]
Unable to parse datatype. NewType.
```
### How was this patch tested?
Added unit test and tested locally.
### Was this patch authored or co-authored using generative AI tooling?
No
