Thorough example for Predicates

[petertonysmith94]

Our documentation lacks a thorough example for predicates (as stated from a forum post).

Is there any complete client side integration example of predicates using Fuels TS-SDK?

@maschad This may be a good one to start digging into predicates.

One idea could be to add to next-steps with how to extend the "Creating a Fuel dApp" docs to both predicates and scripts. So we are not duplicating efforts to much and it should flow quite nicely.

[arboleya]

Sure, but let's also consider making the docs around Predicates more complete in isolation, as we have for Contract.

For instance, if I had a Predicate question, I'd usually search for the Predicate section in the docs.

The create fuels can also cross-link to other parts, as it'll be more of an "all-in-one" thing.

I think @danielbate idea about next steps would directly address this issue. @arboleya the only addition I could see necessary for predicates relative to completeness would be a description of the various methods, which I've added in #2345
