Nested Numbered Headers with Non-Numbered Title Header in My-ST / Sphinx

[cgoebner]

Can anyone help me implement a numbered heading scheme which is like this: myst-parser.readthedocs.io
where the .md headings for an engineering report are structured like this:

Title

heading 1

heading 1 sub

heading 2

etc.

where the numbered output in Sphinx would render like this (the same as the My-ST website) :

Title (not numbered)

1. heading 1
   1.1. heading 1 sub
2. heading 2
   etc.

Instead of what results from use of ":numbered:" in the toc:

1. Title
   1.1. heading 1
   1.2.1 heading sub 1
   1.2. heading 2
   etc.
