Add missing modifier: run2_nanoAOD_106Xv2 for MET significance

[gouskos]

Add missing modifier in 106X relevant for nanoAOD-v9 production.
This makes the MET covariance matrix and MET significance to be identical between 106Xv2 and master [120X] - as they should be

PR validation:

(bug fix for nanov9)

[slava77]

is any of this needed in the master branch?

[gouskos]

No I do not think they are needed in the master. @lathomas @kirschen

[mariadalfonso]

This are already the settings in the master branch.
We backported back then but pipelined only for the nanov8 (run2_nanoAOD_106Xv1), but now we had to set explicitly for the nanov9 run2_nanoAOD_106Xv2 as well. Ideally we should set this as default and then reset for the nanos before UL (while keeping not the default in mini)

for #34096 d6be8dc

• code changes are in line with the PR description and the follow up discussion
  • the changes are specific to nanoAOD. Since this is submitted by XPOG I did not assign to XPOG
• jenkins tests pass and comparisons with the baseline show a difference in the nanoAOD met significance plots in wf 136.8523 (controlled by run2_nanoAOD_106Xv2) as expected

e.g.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
