feat: allow version input to automatically consider the nuances for the Ansys Student version

[RobPasMue]

Description

Allow the Ansys Student version to be considered as a potential option with the same version numbering as the normal versions (according to ansys-tools-path, student versions are negated).

Also taken the opportunity to "remove" support for 23R2 since it was very limited and restricted only to a specific PyAnsys Geometry minor version (0.2 and 0.3).

Closes #1526
