Rename OpenML LGBM & FGBM provider & algorithm names

[AlbertoEAF]

With the introduction of FairGBM now we have LightGBM and FairGBM support in Pulse:

However, in the UI they show up as completely different things, which doesn't give the best UX:

• Microsoft LightGBM - LightGBM Binary Classifier
• Feedzai GBM - FairGBM (LightGBM with fairness constraints)

We could also use the name Feedzai GBM for the LightGBM provider, and at most rename its algorithm to Microsoft LightGBM Binary Classifier, turning into something more organized:

• Feedzai GBM - Microsoft LightGBM Binary Classifier
• Feedzai GBM - FairGBM (LightGBM with fairness constraints)

I also have doubts if FairGBM should also be renamed Binary Classifier, for now it only allows that.
