Use Gradle 7.1 for building Gradle and Intellij plugin (#836)

* Replace usage of 'de.fuerstenau.buildconfig'
with a custom replacement, because the plugin
does not support Gradle 7.0+ and
there has not been any commit activity in 5 years
(https://github.com/mfuerstenau/gradle-buildconfig-plugin);
* Update 'com.github.johnrengelman.shadow' to 7.0.0
