Checkstyle task is not running in the GitHub actions

[dnestoro]

Describe the bug
Locally ./gradlew :utils:checkstyleMain reported some style issues in few files. However, there was no CI failure that would notify us of the style problems on the PR.

Expected behavior
There should be CI check that will give us the same information we would get when using ./gradlew :utils:checkstyleMain (and probably style check for other components as well)
