Remove default for allowed wildcard imports in ktlint_official codestyle

[paul-dingemans]

Expected Behavior
When java.util.* is included as a wildcard import, it should trigger the warning for no-wildcard-imports.
...
Given that, I think it makes sense that ktlint should stop including those two paths as default wildcard exceptions.

The feature to respect setting ij_kotlin_packages_to_use_import_on_demand was implemented not too long ago in ktlint 0.45.x via #1272. The reason for adding the default values is that they seems to be hard-coded in IntelliJ IDEA as well (https://github.com/JetBrains/kotlin/blob/ffdab473e28d0d872136b910eb2e0f4beea2e19c/idea/formatter/src/org/jetbrains/kotlin/idea/core/formatter/KotlinCodeStyleSettings.java#L81-L82).

If the property is not set explicitly, IntelliJ IDEA allows imports java.util.* and kotlinx.android.synthetic.*. If ktlint would not do the same, this would result in a conclict between ktlint and IntelliJ IDEA. Lots of users of ktlint dislike that.

In the new codestyle ktlint_official the default value for allowed wildcard imports shoulbe be cleared.

Removing the default value for code ktlint_official resulted in ktlint to report wildcard imports for java.util.* in case that property ij_kotlin_packages_to_use_import_on_demand is not set. But IntelliJ IDEA interpret the absence of the property differently and stil add the the java.util.* import.

To keep KtLint and IntelliJ IDEA formatter in sync, it is needed to set .editorconfig property below explitcily:

ij_kotlin_packages_to_use_import_on_demand = unset
