fix(API): GT_Fluid (#1349)

* fix(API): GT_Fluid

- Fix: Use registeredFluid instead of GT_Fluid to configure Materials and containers to prevent crashes when retrieving fluids referrences from those.
- Impr: Adjust fluid luminosity computation to better fit with Tungsten as maximum
- Impr: Remove transparency from the fluid.molten.autogenerated.png texture to prevent molten materials to appear dilluted.

* ./gradlew :spotlessApply

* rev(comment): address review comment from @Glease

rev: https://github.com/GTNewHorizons/GT5-Unofficial/pull/1349#pullrequestreview-1098651647

fix: Logic to handle working with own registered fluids and
     already registered fluids.

imp: Some IGT_Fluid methods requires the fluid to be registered,
     throws an IllegalStateException on use at an unregistered fluid.

imp: Normalizes @inheritDoc no additionnal text allowed
