More lua api docs problems

[GlassBricks]

I'm back!
Found a few more inconsistencies in lua-api docs, introduced recently. Last checked in [2.0.63]:

Problems:
- The new BlueprintEntity variant_parameter_groups is missing "rocket_silo", making RocketSiloBlueprintControlBehavior unused.
- In the new TechnologyModifier variant_parameter_groups, there are 2 entries for "vehicle-logistics", and "train-braking-force-bonus" is missing.

Possible Improvements:
- UndoRedoAction's type could be made more specific than "string"

All fixed for 2.0.64, thanks for letting us know.
