[SPARK-51389][BUILD] Allow full customization of profiles in scalastyle

### What changes were proposed in this pull request?

In the `scalastyle` helper script, activate profiles docker-integration-tests and kubernetes-integration-tests in the default value of `SPARK_PROFILES` instead of directly on the `sbt` command line.

### Why are the changes needed?

The `scalastyle` script supports customization of which profiles to activate and check for style violations by passing command-line arguments that fill the `SPARK_PROFILES` environment variable. However, the docker-integration-tests and kubernetes-integration-tests profiles are always activated directly during the `sbt` invocation. This may waste time when engineers want to check for style violations on work in progress that doesn't change any code under these profiles.

### Does this PR introduce _any_ user-facing change?

No. This change only impacts developer tooling. The default behavior of the script when no arguments are passed remains the same.

### How was this patch tested?

In my local repo (not included in this pull request), I introduced style violations in docker-integration-tests and kubernetes-integration-tests. I then ran the script with no arguments, and it flagged the style violations:

```
dev/scalastyle
Scalastyle checks failed at following occurrences:
[error] /usr/local/google/home/cnauroth/git/apache/spark/resource-managers/kubernetes/integration-tests/src/test/scala/org/apache/spark/deploy/k8s/integrationtest/Utils.scala:20:0: java.io. is in wrong order relative to java.nio.file..

[error] Total time: 66 s (01:06), completed Mar 4, 2025, 1:16:42 AM
```

I repeated this with command-line arguments specifying just the yarn profile, but it still flagged the violations in docker-integration-tests and kubernetes-integration-tests:

```
dev/scalastyle -Pyarn
Scalastyle checks failed at following occurrences:
[error] /usr/local/google/home/cnauroth/git/apache/spark/resource-managers/kubernetes/integration-tests/src/test/scala/org/apache/spark/deploy/k8s/integrationtest/Utils.scala:20:0: java.io. is in wrong order relative to java.nio.file..

[error] Total time: 101 s (01:41), completed Mar 4, 2025, 9:04:29 PM
```

After applying the changes in the script, it still flags the violations in docker-integration-tests and kubernetes-integration-tests by default, but not when I specify only the yarn profile:

```
dev/scalastyle -Pyarn
Scalastyle checks passed.
```
