Social Force Model parameters use wrong naming pattern

[schroedtert]

For consistency the naming of the parameters of the Social Force Model should be snake_case as everywhere else.

Hence, create new properties for wrongly named parameters with the correct names and mark the old ones as deprecated. This should then also be ensured with tests, that everything works as intended. If possible add also a ruff check for checking the naming patterns (if only here ignored).

I also noticed that desiredSpeed is actually called v0 in other models. That confused me as well.
