FOund problem: https://github.com/NREL/OpenStudio-workflow-gem/actions/runs/13964989740/job/39093249282?pr=155

Jenkins is still trying to use 2.1.4, and I have no control over it.

The tests are failling on github CI, but that's no related. At least they run.

Failed examples:

rspec ./spec/openstudio/workflow/workflow_analysis_epjson_spec.rb:257 # OSW Integration should run OSW with output requests file
rspec ./spec/openstudio/workflow/workflow_analysis_epjson_spec.rb:647 # OSW Integration should error out while copying html reports
rspec ./spec/openstudio/workflow/workflow_analysis_spec.rb:248 # OSW Integration should run OSW with output requests file
rspec ./spec/openstudio/workflow/workflow_analysis_spec.rb:631 # OSW Integration should error out while copying html reports

$ bundle exec rspec ./spec/openstudio/workflow/workflow_analysis_epjson_spec.rb:257 -e "OSW Integration should run OSW with output requests file"

Needed openstudio-standards for the tests that use measures that use it.
