[SPARK-36068][BUILD][TEST] No tests in hadoop-cloud run unless hadoop…

…-3.2 profile is activated explicitly

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

This PR fixes an issue that no tests in `hadoop-cloud` are compiled and run unless `hadoop-3.2` profile is activated explicitly.
The root cause seems similar to SPARK-36067 (apache#33276) so the solution is to activate `hadoop-3.2` profile in `hadoop-cloud/pom.xml` by default.

### Why are the changes needed?

`hadoop-3.2` profile should be activated by default so tests in `hadoop-cloud` also should be compiled and run without activating `hadoop-3.2` profile explicitly.

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

No.

### How was this patch tested?

Confirmed tests in `hadoop-cloud` ran with both SBT and Maven.
