Compatibility of DaVinci and Analysis in LHCb software development lesson and update of DaVinci version

[vlukashenko]

here it looks like DaVinci/v45r8 would not be anymore compatible with whatever the changes happened in Analysis.

lb-dev DaVinci/v45r8
lb-use Analysis
git lb-checkout Analysis/run2-patches Phys/DecayTreeTuple

will result in

CMake Error at Phys/DecayTreeTuple/CMakeLists.txt:94 (gaudi_install):
  Unknown CMake command "gaudi_install".

It seems that the DaVinci/v46r8 works though - but then need to change the DaVinci version everywhere and check that commands are still working.

Thanks to Emily Kaiyin Jiang for spotting this.
