Convert site to use inline python instead of relying on manual script to generate decision point examples

[ahouseholder]

This PR:

• resolves Replace doctools.py with embedded python examples #431
• resolves Acuity ramp uses out-of-date Safety Impact decision point in example text #539
• eliminates site dependency on doctools.py in favor of direct inline python in the markdown that runs at site deploy time. This change ensures that examples in the site are always the latest available version of any given decision point.
• changes doctools.py as follows:
  • only generates the data/json/decision_points/**/*.json files
  • do not generate docs/_generated/**/*.md since these are replaced by the aforementioned inline python
• Applies a consistent usage of VERSIONS to contain an ordered tuple of all decision point versions defined in a file
• Applies a consistent usage of LATEST to be the most recent version of the decision point (last item in the VERSIONS tuple)

Not a big deal but warning in pedantic seems to indicate that Decision Point Values are expected to be "list" and not "tuple"

SSVC/src/ssvc/decision_points/cvss/helpers.py

Line 37 in 1bb5050

_dp.values = tuple(values)

SSVC/src/ssvc/decision_points/cvss/helpers.py

Line 101 in 1bb5050

_dp.values = tuple(values)

Changing the above two lines in CVSS from "tuple" to "list" - causes the warnings to go away. I have not thoroughly reviewed the scripts but just going after the warnings I saw in "Checks" tab

that say

src/test/test_schema.py::MyTestCase::test_decision_point_group_validation
  /opt/hostedtoolcache/Python/3.10.16/x64/lib/python3.10/site-packages/pydantic/main.py:477: UserWarning: Pydantic serializer warnings:
    Expected `list[SsvcDecisionPointValue]` but got `tuple` with value `(SsvcDecisionPointValue(k...entation for details.'))` - serialized value may not be as expected
    ```

All looks good.
