Correction of Code Smells identified by PMD in the gitlab4j/gitlab4j-api repository

[oliveiraD4vi]

I have identified several Code Smells in the source code of the gitlab4j/gitlab4j-api repository using the PMD tool. The detailed analysis points to specific areas that could benefit from a code review.

I have attached the reports generated by PMD, which include the complete list of identified Code Smells and their respective locations in the code.
