⚠️ Is your feature request related to a problem? Please describe

When checking out the project, there are often changes in idea files that could be ignored since they are set by gradle.

💡 Describe the solution you'd like

Using the https://www.toptal.com/developers/gitignore generator with gradle and intellij recommends ignoring additionally

misc.xml - This is depending on the IDE and java version. And the project can be compiled with java 11 / 17
jarRepositories - this is set by gradle and must not be checked in
gradle.xml - This file is also auto generated with gradle and must not be checked in
compiler.xml - Contains the java version. Changes if someone develops with another java version

🤚 Do you want to develop this feature yourself?
