Update inheritance study to output results separated by language

[DavidRFerreira]

Issue:
The inheritance study results only provide the total number of instances for all languages analyzed.
Therefore, it is impossible to understand how much of that total number is from Kotlin or Java.

Expected Solution:
Create additional columns in the results table to understand the number of Java instances, Kotlin instances, and the total number.
This was already done in the evolution study.

Table Schema:
Evolution Pattern | Java | Kotlin | Total |
