demote LogError about "L1GlobalDecision" in HLTPrescaleProvider

[missirol]

PR description:

This PR is a follow-up of #40481. It demotes the LogError issued by the class HLTPrescaleProvider about "L1GlobalDecision" to a LogDebug message.

This error message, which laments a failure in determining the prescales of the L1T algorithm "L1GlobalDecision", can be seen in the logs of several Run-3 workflows (see #40481 (comment)) [1]. This 'failure' is expected, because "L1GlobalDecision" is not a valid L1T algorithm, but a keyword used mainly by HLT to identify the global decision of the L1T trigger (Final OR, after vetos). For this reason, the LogError call is demoted to LogDebug.

Merely technical. No changes expected. Outputs are unchanged (except for the warning message).

[1] From step 3 of wf 11634.0 in a recent IB:

%MSG-e HLTPrescaleProvider:  PATTriggerProducer:patTrigger  31-Jan-2023 17:18:08 CET Run: 1 Event: 1
 Error in determining L1T prescales for HLT path: 'MC_Run3_PFScoutingPixelTracking_v18' with complex L1T seed: 'L1GlobalDecision' using L1TGlobalUtil: 
 isValid=1 l1tname/error/prescale 1
 0:L1GlobalDecision/0/-1.
%MSG

PR validation:

Checked that the error message disappears as expected in one of the relevant wfs (i.e. wf 11634.0).
