easy-installer: '“java” would like to receive keystrokes from any application' warning on macOS

Summary

When running the easy-installer on macOS 10.15 (Catalina) there is a warning '“java” would like to receive keystrokes from any application'

Description

What is the current behavior?

Before being able to use the easy-installer people will have to change some system preferences. The wording of the warning message might lead people to not wanting to grant the required access which will make the easy-installer unusable for them.

This is caused by a bug in JavaFX 13 which is used by the easy-installer. It should be fixed in JavaFX 14. https://bugs.openjdk.org/browse/JDK-8231513

This behavior was initially reported on the /e/ forum: https://community.e.foundation/t/java-would-like-to-receive-keystrokes-from-any-application/47012

What is the improved behavior?

The warning message does not appear on macOS 10.15 (Catalina) and the easy-installer starts right away.

What does it bring?

A better user experience.

Validation

Execute the easy-installer on macOS 10.15 (Catalina) after this is fixed and verify the warning is gone.
