Update hash_name function for RelMon utilities

[ggonzr]

PR description:

Fixes a compatibility bug between Python 2 and 3 for RelMon HTML report generation. If the parameter --hash_name is set when using ValidationMatrix.py, the scripts fails because it is required to encode the parameter file_name to be hashed as bytes. str is not longer supported.

PR validation:

Some manual tests:

1. Isolate the updated function (hash_name) into another script and use it to hash some strings calling the script using the Python 2.7 and Python 3.11 interpreters.
2. Generate a dummy comparison report with the following .root file: DQM_V0001_R000000001__RelValBuMixing_14__CMSSW_12_4_0-124X_mcRun3_2022_realistic_v5-v1__DQMIO.root, via:

ValidationMatrix.py -R DQM_V0001_R000000001__RelValBuMixing_14__CMSSW_12_4_0-124X_mcRun3_2022_realistic_v5-v1__DQMIO.root -T DQM_V0001_R000000001__RelValBuMixing_14__CMSSW_12_4_0-124X_mcRun3_2022_realistic_v5-v1__DQMIO.root -o Test_Report --hash_name --standalone

[tjavaid]

@ggonzr , can this update cause (though very minute i.e. a couple of entries) differences for the WF 9.0 ? (bin-by-bin)

[ggonzr]

Hello @tjavaid,
No, This update is only related to the compatibility with Python 3, the behavior for computing the hash remains the same, so no issues are expected from this.

[tjavaid]

@ggonzr , thanks for confirming. @mmusich just pointed out an issue (#43415) on this randomly appearing WF causing differences. We can sign this now.
