Modified conditions to fix incorrect HLT JEC [11_1_X]

[christopheralanwest]

PR description:

This PR is a backport of PR #30221. The GT diffs are the same as in the PR to master.

Negative HLT jet energies have been reported in Run-3 samples. The problem has been traced to the fact that Run-3 GTs currently load the 2016 HLT JECs, while it should actually make use of the 2017 HLT JECs.

if this PR is a backport please specify the original PR and why you need to backport that PR:

This PR is a backport of #30221. It is needed because the HLT JEC conditions currently used in the Run-3 GTs are incorrect.

• Identical GT diff as in PR to master
• Changes validated in local tests
• Comparison tests show differences only in expected workflows (11634.0 and 12434.0) and only in the expected histograms (HLT histograms only)

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_11_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo (and backports should be raised in the release meeting by the corresponding L2)
