when it says that gaseous hydrogen sulfide is bubbled through a solution of nickel (II) Nitrate, does it mean that Hydrogen Sulfide is soluble as well? or is it insoluble?

It means that a stream of the gas is introduced into the bottom of the flask containing the nickel nitrate solution, and rises through the solution as bubbles (the smaller the bubbles, the better). This is the usual way to get a gas to dissolve in a liquid. Usually gases are only sparingly soluble in liquids (for example, the saturation concentration of oxygen in water is 8 mg/L). So any chemical reaction involving a dissolved gas usually requires the gas to be added continuously as a stream of bubbles, as the dissolved gas is used up by the reaction as fast as it can dissolve into the liquid.
If you want a mundane example of this, think of an aquarium, where oxygen is added to the water in an aquarium bubbler, and is continuously used up by the fish and the bacteria living in the water.

Hydrogen Sulfide is soluable in water. The solubility is dictated by Henry's Law.

It's basically saying that when you go to write the chemical reaction's equation, you should write H2S on the reactant side as opposed to 2H+ + S2-

Some will probably dissolve but most will 'bubble through'
