Updating FCC-ee mH recoil mumu example to work with edm4hep v1 format

[bistapf]

The commits in this PR update the example mH recoil analysis from the FCCSW tutorial to work with the updated edm4hep event data model. Few things to be noted:

• The updated edm4hep v1 style is only available from setting up the nightlies of key4hep (in current version v00-99, which should already be stable and equivalent towards the official release of v1). Hence the setup script as well as the build&test are adapted to using only the nightlies temporarily and an updated input file.
• The new tester files in edm4hep v00-99 were produced with k4SimDelphes according to the tutorial and are available in the FCC-hh eos space area and reading the officially produced samples is overwritten in the example.
• The analysis files as described in the tutorial, section 2.3.1 are added to the respective example directory as well.
• The plot making step currently does not work out of the box due to problems in do_plots.py to be fixed in PR#397 - otherwise everything should run.
• This is is a first technically working version for edm4hep v1, whether the more intricate code like getting MC<->Reco relations is still working as intended is to be confirmed.

You are missing ' at the end. So the line should end like this:
