Update language detection for SAST NO_DIND spotbugs coverage

What does this MR do?

Fixes bug in spotbugs analyzer's language detection. Before this fix the target languages of scala and groovy were excluded for SAST scans when using SAST_DISABLE_DIND mode. This MR realigns the detection logic with spotbugs plugin detection logic.

Fixes #119092 (closed)

Groovy

NOTE: We could not use the standard tests/java-groovy project since it includes Java and we wanted to test a pure-groovy detection
