Is your task related to a problem? Please describe

Gateway connector plugin uses IntelliJ Platform Gradle Plugin. Recently a major update was released https://github.com/JetBrains/intellij-platform-plugin-template/pull/458 It broke the Gateway plugin build as it gets some updates through the dependabot, but updating to a major update requires manual work described in https://plugins.jetbrains.com/docs/intellij/tools-intellij-platform-gradle-plugin-migration.html#plugin-name-change

I fixed the issue preventing the plugin from being built https://github.com/redhat-developer/devspaces-gateway-plugin/commit/395ecddaee3412578100b772c020db4c7ea28f1e

Currently, it doesn't block and can be done in the next iteration.
