do not throw exception in Trigger{Bx,Rates}Monitor if L1-uGT results are unavailable [13_1_X]

[missirol]

backport of #41568

PR description:

From the description of #41568:

This PR updates the plugins Trigger{Bx,Rates}Monitor in order to avoid that a ProductNotFound exception is thrown if the product containing the L1-uGT results is not available.

The exception is replaced with a LogError message (this follows what is already done in another somewhat-similar HLT plugin, namely L1TriggerJSONMonitoring).

These two plugins are used online in the HLT menu to produce outputs for the online DQM.

This PR relates to #41512 (comment), and it might be relevant to current online operations. For this reason, it will be backported down to the 13_0_X release cycle.

PR validation:

None beyond the checks done for #41568.

If this PR is a backport, please specify the original PR and why you need to backport that PR. If this PR will be backported, please specify to which release cycle the backport is meant for:

#41568

Improvement to 2 plugins used online in the HLT menu.

This pull request is fully signed and it will be integrated in one of the next CMSSW_13_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_13_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
