#6945 Increase minimum eclipse version for actifsource

Actifsource code generator for any programming language
In order for Actifsource to use the new features of Eclipse without restrictions, the minimum Eclipse version must be increased.
The minimum Eclipse version is now 4.26.0 (2022-12) with Java 17 which is also the minimum Java version of Eclipse 4.26.0.
In addition, all dependencies (plugins and libraries) have also been increased to these minimum requirements.

When installing this version, a new Eclipse should be used which does not yet contain any older Actifsource plug-ins. This increases the speed of installation.
