Please fix infer PR check

[Hardvan]

I think the infer check is failing because I added a new dependency (mockito) in the pom.xml file. Mockito is needed for mocking the random number generator in the test cases.

[siriak]

It says
src/main/java/com/thealgorithms/scheduling/LotteryScheduling.java:56: error: Null Dereference(NULLPTR_DEREFERENCE)
selectedProcess could be null (from the call to LotteryScheduling.selectProcessByTicket(...) on line 54) and is dereferenced.
54. Process selectedProcess = selectProcessByTicket(winningTicket);
55.
56. > selectedProcess.setWaitingTime(currentTime);
57. currentTime += selectedProcess.getBurstTime();
58. selectedProcess.setTurnAroundTime(selectedProcess.getWaitingTime() + selectedProcess.getBurstTime());

[Hardvan]

I have fixed the bug.
