Fix JaCoCo Java 18 compatibility and test case failures

[AniketDev7]

JaCoCo Java 18 Compatibility

• Issue: JaCoCo plugin version 0.8.7 was incompatible with Java 18, causing java.lang.instrument.IllegalClassFormatException in GoCD pipeline
• Fix: Updated JaCoCo plugin version from 0.8.7 to 0.8.13 in pom.xml
• Root Cause: Older JaCoCo versions don't support Java 18's enhanced class format
• Impact: Tests now run successfully in GoCD pipeline with OpenJDK 18

Test Case Failures

• Issue: Two test cases were failing due to case sensitivity mismatch in JSON file paths
• Fix: Updated file paths in TaxonomyAPITest.java from mockTaxonomy/ to mocktaxonomy/
• Files Changed:
  • src/test/java/com/contentstack/cms/stack/TaxonomyAPITest.java
  • src/test/resources/mocktaxonomy/createTerm.json
  • src/test/resources/mocktaxonomy/updateTerm.json
• Root Cause: Test code was referencing mockTaxonomy/ but actual directory was mocktaxonomy/
