🐞 Description of the bug

When using the new load_templates method on the ADR service class, to import a report template from a JSON file, you get errors if the template to be imported is of merge table generator type.

test_report.json

📝 Steps to reproduce

Use pydynamicreporting to start / connect to a running service:

import ansys.dynamicreporting.core as adr
a = adr.Service(db_directory=r'''D:\tmp\test''')
a.start(create_db=True)

Now, load the attached json file:
a.load_templates(r'''D:\tmp\test_report.json''')

This returns this error:

File "c:\ansysdev\nobackup\pyansys\pyadr\src\ansys\dynamicreporting\core\utils\report_remote_server.py", line 1155, in _check_template
raise exceptions.TemplateEditorJSONLoadingError(
ansys.dynamicreporting.core.utils.exceptions.TemplateEditorJSONLoadingError: The loaded JSON file has an invalid 'report_type' value: 'Generator:tablemerge'

The template type is actually valid.
