Publish action failing for the SPDX 3.0 support branch

Triggering the publish_v3 action for the support branch results in the following error:

Run python3 spec-parser/main.py spdx-3-model/model $PARSER_OUT_BASE_DIR
usage: main.py [-h] [-d] [-f] [-j] [-J OUTPUT_JSONDUMP] [-m]
               [-M OUTPUT_MKDOCS] [-n] [-o OUTPUT] [-p] [-P OUTPUT_PLANTUML]

Need to update the GitHub workflow in the support branch to keep up with the changes in the spec-parser command line interface.
