Clarify doc build dependencies w.r.t. /src/SSVC_csv-to-latex.py

[ahouseholder]

@j--- commented in #276:

Just tracking that we need to rerun https://github.com/CERTCC/SSVC/blob/main/src/SSVC_csv-to-latex.py to update the graphics after this pull is accepted.

Which highlights a build process dependency I had not previously recognized.

csv[tree.csv]

I think the rule we need to construct is something like:

When any .csv in /data/csvs changes do

for csv in csvs:
  run  /src/SSVC_csv-to-latex.py #  need to define correct command args
  # I don't mean literally command args, I mean more like either wrap or refactor `SSVC_csv-to-latex.py` to build all the docs correctly by default, but that requires us to understand how to use it to generate the `.tex` files and `.pdf`
  run latexmk
  git add and commit changes

This seems like a mod to /doc/Makefile and once we work out the steps add the appropriate mods to /.github/workflows/pandoc_html_pdf.yaml

See this comment in #276 for specific command line examples.

Given the change to the web site as the primary documentation target instead of PDF-building, I think this issue is now moot and can be closed as wontfix. I'm leaving it open for a bit longer to allow for counterarguments, but let's set a timer that it can be closed after 2023-10-13 if no such reasons are forthcoming.
