Fixed Satisfy Number Case Rule Bug

[busabj]

Description

In SatisfyNumberCaseRule.java, in the second generateCases() method, I added a loop and conditional checking for adjacent cells without lightbulb and changing them to be dotted. For context, there was an issue in the LightUp game where the Satisfy Number rule was not doing as it should. It is supposed to make cells adjacent to a number cell that are not a light bulb into a dotted cell. It was not making the cells dotted, so only the light bulb cell was showing up.

Closes #565

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Enhancement (improvement to an already existing feature)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How Has This Been Tested?

To test this, I ran different boards and used the Satisfy Number case rule on different numbered cells. I checked all the produced cases, and the correct cells were now dotted.
To reproduce, open lightup, 7x7 Easy, board 393454, click Case Rules, click Satisfy Number, then click any numbered cell.
