Fix deprecated Intellij API usages (#2554)

* Update Intellij Gradle plugin

* Drop support for Intellij < 2021.3

The latest stable Android Studio (Dolphin) is based on 2021.3,
so we can drop support for older versions.

* Remove usages of deprecated Intellij APIs

* Remove upper Intellij version limit
