WIP: OSOE tutorial amendment

This MR will get continually update for a while base on the potential OSOE feedback. Currently, it includes:

• wild card update in template_keep_last_workflow_history_only_path_list(Some how we can't see the template_keep_last_workflow_history_only_path_list from the MR. But I can see the change from the git diff in a terminal...)
• Remove the surrounded <p> tag of them <img> tag.

The infix wildcard only works on the normal Path, aka my_template_path_list:

image_module/user_howto_*_new
web_page_module/osoe_howto_*_svg
web_page_module/user_howto_*_svg

I have to use the suffix wildcard in the field template_keep_last_workflow_history_only_path_list:

image_module/user_howto_**
web_page_module/osoe_howto_**
web_page_module/user_howto_**
