Documentation issue for mspass schema page

[pavlis]

I've been picking away at various issues in our documentation pages. Running sphynx with the dev container I got this error:

home/source/mspass_schema/mspass_schema.rst:54: CRITICAL: Problems with "csv-table" directive path:
[Errno 2] No such file or directory: 'source/mspass_schema/all.csv'.

.. csv-table:: **All MsPASS Attributes**
   :file: all.csv
   :widths: 12,5,5,50
   :header-rows: 1
/home/source/mspass_schema/mspass_schema.rst:66: CRITICAL: Problems with "csv-table" directive path:

followed by several similar message about missing csv files. I think the two python scripts in docs/source/mspass_schema are supposed to create these files, but the master copy of the "mspass schema" page on mspass.org is missing the tables that these files are supposed to generate. I am not sure how to fix this or I'd just do it. There is either a missing script to run the required python scripts or we need to put the required csv files in the repository.
