fix issue with DQMGlobalEDAnalyzer skeleton (mkdqmedanalyzer command)

[mmusich]

PR description:

I noticed recently that the code generated with the command:

 mkdqmedanalyzer -author mmusich Test example_global

didn't compile due to the removal of ConcurrentMonitorElement and DQMStore::ConcurrentBooker in #28092.
This PR changes the skeleton in order to generate code that compiles.

PR validation:

Used the command above with this branch and obtained compiling code.

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

Not a backport, no backport needed.
