fix minimum of the di-muon mass window in the Z->mm validation tool

[mmusich]

PR description:

It was recently noticed by @TomasKello that the default mass window range in the python configuration of the ZMuMu validation tool was in the range [80-120] GeV.
Restricting the mass fits in this asymmetric region around the Z mass peak ends up biasing the output fit parameters, as illustrated e.g. this plot:

This in turn created some unphysical features in the distribution of the invariant mass peak position as a function of the muon kinematic that are used to validate the various alignments.
The goal of this PR is to allow the fit to cover the whole region [60-120] GeV as default value in the all-in-one tool configuration, as already done in the fillDescriptions method of the plugin, see:

cmssw/Alignment/OfflineValidation/plugins/DiMuonValidation.cc

Lines 380 to 381 in 3914bc8

	desc.add<double>("Pair_mass_min", 60.);
	desc.add<double>("Pair_mass_max", 120.);

PR validation:

The tool was run in the vanilla release and the newly proposed defaults.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @sextonkennedy, @rappoccio, @antoniovilela, @mandrenguyen (and backports should be raised in the release meeting by the corresponding L2)
