[Speedgrader] Add AI Score Next To Originality Score

[PlagiarismCheck]

Problem statement:

Speedgrader contains a parameter for similarity originality_report[originality_score]. However, now we have AI detectors that provide another score based on the same work, so teachers ask for it to be displayed together with the originality score.

Proposed solution:

Add parameter originality_report[ai_score] to Speedgrader near the originality_score with the same color-code
