[SPARK-49941][CORE] Rename errorClass to condition in errors of the JSON format

[MaxGekk]

What changes were proposed in this pull request?

In the PR, I propose to rename the errorClass to condition in errors in the JSON formats: MINIMAL and STANDARD.

For example:

{
  "condition" : "DIVIDE_BY_ZERO",
  "sqlState" : "22012",
  "messageParameters" : { "config" : "CONFIG"}
}

Why are the changes needed?

To follow new naming convention introduced by #44902.

Does this PR introduce any user-facing change?

Yes.

How was this patch tested?

By running the affected tests:

$ build/sbt "sql/testOnly org.apache.spark.sql.SQLQueryTestSuite"

Was this patch authored or co-authored using generative AI tooling?

No.

@srielau @panbingkun @nchammas @cloud-fan Could you review the PR, please.

[panbingkun]

LGTM.
nit: Do we need to update the following?

[MaxGekk]

@panbingkun Thank you for review.

1. UIUtils: The name errorClass is regexp group name. Not related to the changes.
2. SQLJsonProtocolSuite: it is just an example in a test. It could handle old input.

[panbingkun]

1. UIUtils

Yeah!

• Yes, it is indeed the group name of a regular expression. Not related to the changes, and calling it as errorClass will not affect the final functionality.
  (PS: As a follow-up, I'm not sure if we need to rename it to condiiton to reduce misunderstandings? Because from UT, it seems that its purpose is to obtain the value of condiiton (In the past, it was called errorClass)

  (Because after this PR, I believe that in the error log, there should only be condiiton and no errorClass.)
• Okay.

[nchammas]

LGTM, but is there a summary of why we are going with condition rather than errorCondition?

I remember seeing a discussion somewhere about this, but it's not on the ticket associated with this PR.
